Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. Tonsillitis is assessed by video with a look at the tonsils on camera; antibiotics are prescribed when bacterial criteria are met, and severe one-sided pain, drooling or trouble opening the mouth needs emergency care.
- What it is: inflammation of the tonsils, viral in about 7 in 10 cases and caused by group A strep in most of the rest; most common in children and young adults, but it occurs at any age.
- Bacterial signs: high fever, pus on the tonsils, tender neck glands, rapid onset and no cough make a bacterial cause more likely; a runny nose and cough point to a virus.
- How long: viral tonsillitis settles within about a week; bacterial tonsillitis treated with antibiotics improves noticeably within 2 to 3 days, though the course must be finished.
- Quinsy: severe one-sided pain, drooling, a muffled voice or trouble opening the mouth suggests an abscess beside the tonsil that needs emergency drainage, not a booking.
- Emergency: if you are struggling to breathe, call 112.
If your pain is severe on one side, you cannot open your mouth properly, cannot swallow your own saliva or are drooling, or your voice has gone muffled, this may be quinsy, an abscess beside the tonsil. Go to emergency care now rather than booking online. If you are struggling to breathe, call 112.
Can an online doctor treat tonsillitis?
Yes. On Mobi Doctor, a licensed doctor can assess tonsillitis by video: the tonsils are visible on camera, so the doctor can see the swelling, spots and asymmetry that guide treatment, and prescribe antibiotics where the criteria are met.[1] Suspected quinsy, with severe one-sided pain, drooling or a muffled voice, needs emergency care.
That visibility is the point. Unlike a cough or a fever, tonsillitis presents its evidence to a camera, which means an online doctor is not working blind: they are working from the same visual signs a clinic doctor starts with, plus the symptom criteria that carry most of the decision anyway.

How an online consultation helps with tonsillitis
- The doctor can see your tonsils: with good light and the camera close, swelling, redness, white spots or pus, and one-sided versus both-sided change are all visible, the evidence that separates tonsillitis from a plain sore throat.
- Viral or bacterial, decided on criteria: fever, pus on the tonsils, tender neck glands, speed of onset and the absence of a cough, the same structured cues doctors use in clinic, applied to you, with the reasoning explained.[1]
- Antibiotics when the criteria are met: most tonsillitis is viral and antibiotics are only prescribed when there are signs of bacterial infection; where they are, a prescription goes to a local pharmacy.
- A plan for repeat offenders: if this is your third or fourth episode, the doctor helps you document the pattern properly and starts the referral conversation, rather than treating each bout as if it were the first.
📷 Before your appointment, take one or two photos of your throat in daylight or with your phone torch: mouth wide, tongue flat, camera close. During the call the doctor can also watch a short live look. Clear pictures of your tonsils make the assessment noticeably better.
What the doctor checks in an online tonsillitis consultation
A tonsillitis consultation is evidence-based in a literal sense: you show the doctor your tonsils and answer the questions that decide whether antibiotics will help. In a tonsillitis consultation the doctor will typically check:
- The tonsils on camera: swelling, redness, white spots or pus, and whether one side is worse than the other.
- Fever: whether you have had one, and how high.
- Cough and cold symptoms: their absence points towards a bacterial cause, their presence towards a virus.[1]
- Neck glands: the doctor may coach you to press gently below the jaw and describe whether they are tender and swollen.
- Mouth opening and swallowing: whether you can open fully and manage saliva and fluids, both of which are quinsy flags when restricted.
- How many episodes you have had: duration now and the number this year, which feeds the recurrent-tonsillitis pathway.
- Background: your regular medicines, any penicillin allergy, and pregnancy status.
What are the symptoms of tonsillitis?
Tonsillitis causes a sore throat that is worse on swallowing, red and swollen tonsils, often with white spots or a coating, fever, tender glands in the neck, bad breath and a thick or muffled voice. Ear pain and headache are common companions. Symptoms usually build over a day or two.
- Throat pain that peaks on swallowing: eating and drinking become the hard part of the day.
- Red, swollen tonsils: visibly larger than usual on both sides in typical tonsillitis.
- White spots, streaks or a coating: the classic clue that shifts suspicion towards a bacterial cause.
- Fever and shivers: more prominent in bacterial tonsillitis than viral.
- Tender lumps below the jaw: swollen lymph glands doing their job.
- Bad breath and a thick voice: both settle as the tonsils do.
- Ear pain on swallowing: referred from the throat; it does not necessarily mean an ear infection.
Viral or bacterial tonsillitis?
Most tonsillitis is viral and clears within about a week with painkillers and fluids; antibiotics do not help these cases. Bacterial tonsillitis, usually strep, is more likely when high fever, pus on the tonsils and tender neck glands appear quickly without a cough, and that is when antibiotics earn their place.[1]
Viral, the majority
Most tonsillitis arrives as part of a cold-type illness: sore tonsils alongside a cough, runny nose or hoarseness, improving within about a week with painkillers and fluids. Antibiotics change nothing here, because the cause is a virus.
Bacterial, usually strep
Bacterial tonsillitis tends to be faster and fiercer: high fever, intense pain on swallowing, white spots or pus on the tonsils, tender glands in the neck, and typically no cough. The more of these features you have, the more likely antibiotics are to genuinely shorten the illness, and that is exactly the calculation the doctor makes with you on screen.
When it is glandular fever instead
In teenagers and young adults, hugely swollen tonsils plus exhaustion that lasts weeks and prominent neck glands can mean glandular fever rather than ordinary tonsillitis. The distinction matters: doctors avoid amoxicillin when glandular fever is suspected, because in that illness it commonly causes a widespread rash.
Is my tonsillitis suitable for online care?
Most tonsillitis is well suited to video care, because the tonsils are visible; a minority needs in-person care instead. The table below shows how doctors sort it into self-care, an antibiotic where criteria are met, and referral.
Swipe sideways to compare →
| Tonsillitis presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Viral tonsillitis with cold symptoms | Self-care: regular painkillers, fluids and rest | Usually yes | If not clearly improving after about a week |
| Likely bacterial (high fever, pus on tonsils, tender glands, no cough) | Assess criteria; antibiotic where they are met[1] | Usually yes | Penicillin allergy needing an alternative, or no response to treatment |
| Recurrent tonsillitis, several episodes a year | Confirm and document the episode; discuss referral | Yes, for assessment and documentation | ENT referral for possible tonsillectomy when frequent and disruptive over a year |
| Severe one-sided pain, drooling, muffled voice, trouble opening the mouth | Emergency care (possible quinsy) | No | Same-day emergency assessment; call 112 if breathing is affected |
| Cannot keep fluids down, or a child who is drowsy or breathing noisily | Urgent in-person care | No | Same-day in-person review; call 112 if breathing is affected |

See available times →How long does tonsillitis last?
Viral tonsillitis usually settles within about a week. Bacterial tonsillitis treated with antibiotics typically improves noticeably within two to three days, though the full course must still be finished. If your symptoms are not improving after three to five days of treatment, or are worsening at any point, book a review.
Worsening has a specific meaning here: pain concentrating on one side, growing difficulty opening the mouth or swallowing, a voice going muffled. Those are quinsy signals, and they convert a wait-and-see plan into an emergency-department visit, which is exactly why the doctor spells them out before the call ends.
Recurrent tonsillitis: getting off the carousel
Some adults get tonsillitis again and again, several confirmed episodes a year, each costing a week of work or study. If that is you, two things help. First, documentation: keep dates, symptoms, photos and any antibiotic courses, and have each episode confirmed by a doctor, because referral decisions rest on documented episodes rather than memory. Second, the referral itself: when episodes are frequent and genuinely disruptive over more than a year, an ear, nose and throat specialist can discuss whether tonsillectomy is worth it. An online doctor cannot remove tonsils, but they can confirm episodes as they happen, build that record with you, and write the referral letter where appropriate.
Honesty about prevention: there is no proven way to stop recurrent tonsillitis with lifestyle changes. Sensible hygiene reduces the infectious load, with hand-washing, not sharing cups and cutlery, and staying home while feverish, and not smoking keeps the throat less irritable, but if episodes keep coming despite that, the documented-episodes route is the one that leads somewhere.
When it might be something else
Tonsil stones
White or yellow gritty lumps on the tonsils without pain or fever are usually tonsil stones, trapped debris in the tonsil crevices, annoying and smelly but harmless. They cause bad breath and a foreign-body feeling, not illness. Gargling helps; antibiotics have no role. If you are unsure whether you are looking at stones or infection, a photo plus a video consultation settles it quickly.
One tonsil bigger than the other
During infection, some asymmetry is common and usually settles as you recover. A tonsil that stays clearly enlarged after recovery, keeps growing, or develops an ulcer, particularly in smokers, needs an in-person ear, nose and throat examination to rule out rarer causes. That is a firm referral the online doctor will make, not a watch-and-wait.
Special situations
Tonsillitis in children
Children get tonsillitis often, and the same viral-versus-bacterial logic applies, sometimes with tummy ache and refusal to eat standing in for the complaints an adult would voice. Mobi Doctor does not see children at the moment, so a child with suspected tonsillitis should be assessed in person by a paediatrician or a local doctor; for small children who are drooling, refusing all fluids, becoming drowsy or breathing noisily, go straight to in-person care now.
Tonsillitis in pregnancy
Paracetamol is the preferred painkiller in pregnancy; ibuprofen is generally avoided, particularly in the third trimester. Where bacterial criteria are met, tonsillitis is still treated: penicillin-type antibiotics are among those commonly used in pregnancy, chosen case by case after assessment. Fever plus struggling to keep fluids down in pregnancy lowers the threshold for an in-person review.
Tonsillitis while travelling
Tonsillitis has a talent for arriving mid-trip. A video consultation solves the practical problems: an English-speaking doctor, any prescription routed to a pharmacy near where you are staying, and a written record of the episode, which matters more than it seems if you are heading towards a recurrent-tonsillitis referral and need every episode documented.
Treatment options for tonsillitis
What you can do yourself
Take paracetamol or ibuprofen regularly for the first days, because steady pain control is what makes drinking and sleeping possible. Keep fluids going little and often; cool drinks and ice lollies often go down easier than hot ones. Adults can add medicated lozenges or an anaesthetic throat spray, and a warm salt-water gargle if it soothes.[5] Rest, and stay home while feverish, because the infections behind tonsillitis spread through coughs, sneezes and close contact.
What does not help
Leftover antibiotics from a previous course are a bad idea twice over: they are usually the wrong drug or duration for what you have now, and half-treating an infection muddies the assessment while feeding antibiotic resistance. Equally unhelpful: cutting fluids because swallowing hurts, because dehydration is one of the main reasons adult tonsillitis ends up needing in-person care, and smoking through an episode, which keeps the throat inflamed for longer.
Prescription treatment
A prescription is never issued without a consultation. When enough bacterial-pointing criteria are met on assessment, the doctor will usually prescribe a penicillin-type antibiotic, so tell them about any penicillin allergy so an alternative can be chosen, and finish the course even once you feel better.[2] Antibiotics are only prescribed when there are signs of bacterial infection: they do nothing for viral tonsillitis, and unnecessary courses drive antibiotic resistance.[3][4] Whatever is decided, you get a clear safety net: what should improve within three to five days, and what to do if it does not.
When tonsillitis is treated online, and when you need in-person care
Treated online: viral tonsillitis needing self-care and clear safety-netting; likely bacterial tonsillitis meeting the criteria for antibiotics; recurrent episodes the doctor can confirm and document towards a referral; and tonsil stones, which the doctor can identify and reassure you about.
In-person care: suspected quinsy, with severe one-sided pain, drooling, a muffled voice or trouble opening the mouth, which is an emergency; anyone who cannot keep fluids down or is becoming dehydrated; a tonsil that stays enlarged after recovery, keeps growing or develops an ulcer, especially in smokers, which needs an in-person throat examination by an ENT specialist; small children who are drooling, refusing all fluids, drowsy or breathing noisily; and frequent, disruptive recurrences over more than a year, where an ENT referral for tonsillectomy is the honest next step.
When to get in-person care
Go to emergency care for possible quinsy: severe one-sided pain, difficulty opening your mouth, a muffled voice, or being unable to swallow saliva. Get urgent review if you cannot keep any fluids down or are becoming dehydrated. If you are struggling to breathe, making a high-pitched noise when breathing in, or becoming drowsy or confused, call 112 immediately.
Treating tonsillitis at home: what helps and what does not
Most tonsillitis is viral and settles within about a week with rest, fluids, simple pain relief, salt-water gargles and lozenges. Home care is genuinely the right start for a mild sore, swollen throat.
What home care cannot do: it cannot tell viral tonsillitis from the streptococcal kind that justifies antibiotics, and it cannot manage complications. Severe one-sided pain, difficulty opening the mouth, drooling or a muffled voice suggests an abscess forming behind the tonsil, which is an emergency. Tonsillitis returning several times a year is also worth a proper review rather than another week of gargling.
Staying at home is the point of Mobi Doctor: you can see a licensed doctor over video, usually within 15 minutes, with no waiting room. If medication is the right answer, the prescription follows. Book a video consultation: the exact price is shown before you pay.
Is tonsillitis contagious?
The infections behind it are. Tonsillitis itself is inflammation, but the viruses and strep bacteria that cause it spread through coughs, sneezes and shared glasses, which is why it runs through households and classrooms.
How long are you infectious? Viral tonsillitis roughly while symptoms are at their worst; strep tonsillitis typically stops being infectious about 24 to 48 hours after antibiotics begin, which is often the practical argument for treating it. Untreated strep can spread for longer.
Glandular fever can look identical in the throat and lingers far longer; there is more on the glandular fever page.
How Mobi Doctor works
- Book a time that suits you: open daily 7am–11pm CET. You can see a doctor over video, usually within 15 minutes. No subscription, exact price up front.
- Upload your throat photos, then speak to a licensed doctor: a private video call: you describe what you feel, the doctor asks what matters, and you agree the right plan together.
- Leave with your plan: everything agreed before you hang up: your plan, and a prescription to use at a pharmacy near you where medication is clinically right for you. If your doctor decides you need to be seen in person, you get a full refund.

Frequently asked questions about tonsillitis
What is tonsillitis?
Tonsillitis is inflammation of the tonsils, the two glands at the back of the throat that help fight infection. It causes a severe sore throat, pain on swallowing, fever, swollen red tonsils often with white spots or pus, and tender glands in the neck. Most tonsillitis is viral and settles within about a week; a minority is bacterial and responds to antibiotics.
What causes tonsillitis?
Tonsillitis is caused by the viruses behind colds, flu and glandular fever in about seven out of ten cases, and by bacteria, mostly group A streptococcus, in the rest. The infection spreads by coughs, sneezes and close contact. Tonsillitis is commonest in children and young adults because their tonsils are larger and more active, but anyone can get it.
What are the symptoms of tonsillitis?
Tonsillitis brings a sore throat that makes swallowing painful, red and swollen tonsils often with white or yellow spots, fever, headache, earache, tender swollen glands in the neck, bad breath, tiredness and sometimes a hoarse voice. Children may have stomach ache and vomiting. Symptoms usually peak within two to three days.
Do I need antibiotics for tonsillitis?
Often not. Most tonsillitis is viral and settles within about a week with painkillers and fluids. Antibiotics earn their place when several bacterial-pointing features line up (high fever, pus on the tonsils, tender neck glands, no cough), and the doctor shows you exactly which of them you have rather than prescribing on request.
Can an online doctor prescribe antibiotics for tonsillitis in Europe?
Yes, an online doctor can prescribe antibiotics for tonsillitis where the assessment shows signs of a bacterial infection: high fever, pus on the tonsils, tender neck glands, no cough. Antibiotics are not prescribed for viral tonsillitis, because they do not work against viruses; when one is right, the prescription goes to a pharmacy near you.
Can tonsillitis really be assessed over video?
Better than most conditions: tonsils are visible, so photos plus a live camera view give the doctor real evidence of tonsillitis to work from. What video cannot do is a throat swab or physical examination, and if your picture is unclear or there are signs of an abscess, the doctor directs you to in-person care rather than guessing.
How long does tonsillitis last?
Viral tonsillitis usually settles within a week, with the worst pain in the first two to three days. Bacterial tonsillitis improves noticeably within two to three days of starting antibiotics, though the course must be finished. Tonsillitis caused by glandular fever can last two to three weeks, and tonsils that stay sore beyond that need an in-person examination.
Is tonsillitis contagious?
The viruses and bacteria that cause tonsillitis spread through coughs, sneezes and close contact, so wash hands often, avoid sharing cups and cutlery, and stay home while you have a fever. You are much less infectious once the fever has gone, and with bacterial tonsillitis after about a day of antibiotics.
How do I treat tonsillitis at home?
Treat tonsillitis at home with paracetamol or ibuprofen taken regularly, plenty of fluids, salt-water gargles, lozenges or a numbing throat spray, and rest. Cool, soft food little and often goes down easiest: cold drinks, ice lollies, yoghurt, smoothies and lukewarm soups, eaten 30 to 45 minutes after painkillers. If you genuinely cannot keep fluids down, you need in-person care.
When is tonsillitis an emergency?
Tonsillitis becomes an emergency when it turns into quinsy, an abscess beside the tonsil: severe pain on one side, trouble opening the mouth, a muffled voice, drooling or being unable to swallow saliva. Go to emergency care rather than booking online, and call 112 if breathing is difficult or noisy.
When is tonsil removal considered?
Tonsillectomy is discussed when documented episodes of tonsillitis are frequent and disruptive, typically seven in one year, five a year for two years, or three a year for three years; it is a specialist decision weighing surgery against the burden of recurrences. An online doctor can confirm and document your episodes and write an ear, nose and throat referral.
Are tonsil stones the same as tonsillitis?
No. Tonsil stones are gritty white or yellow lumps of trapped debris that cause bad breath and an odd feeling in the throat, without fever or real pain; they are harmless and never need antibiotics. Tonsillitis is an infection: painful, feverish, with swollen tonsils, and it settles within a week or with antibiotics when bacterial.
Is tonsillitis different in adults, pregnancy or with a weakened immune system?
Adult tonsillitis is less common than in childhood but often more painful, and glandular fever is a frequent cause in people under 30. In pregnancy, tonsillitis is treated with paracetamol, fluids and, when bacterial, antibiotics safe in pregnancy; ibuprofen is avoided. With a weakened immune system, the threshold for antibiotics and in-person review is lower.
How can I prevent tonsillitis coming back?
Prevent repeat tonsillitis by washing hands often, not sharing cups, bottles or cutlery, replacing your toothbrush after an infection, not smoking, and finishing any antibiotic course prescribed. Recurrent bacterial tonsillitis in a household sometimes comes from a strep carrier, which a doctor can test for; frequent documented episodes may justify a tonsillectomy referral.
