- Treated online: Sometimes. Fungal infections treated online; spreading infection and diabetic feet go in person.
- Athlete’s foot is usually treatable online; any foot infection in someone with diabetes needs same-day in-person care, always.
- Athlete’s foot itches and peels slowly, usually on both feet; a hot, painful, spreading area suggests bacterial infection instead.
- Thickened, crumbly, yellow-brown nails suggest fungal nail infection, which takes months to treat and often needs lab confirmation.
- Athlete’s foot that keeps returning usually means shoes and socks are reinfecting the skin; treating both breaks the cycle.
If you have diabetes, do not book an online consultation for a foot problem: go to in-person care the same day. Any new redness, swelling, warmth, discharge, ulcer or wound on a diabetic foot can threaten the limb and needs urgent physical examination.[1] The same applies to anyone with redness spreading up the foot or leg, fever, a deep or smelly wound, or a foot that is suddenly cold, numb or discoloured. Itchy, peeling skin between the toes, without those features, is well suited to online care.
Can an online doctor treat a foot infection?
It depends on which kind. Fungal infections such as athlete's foot can usually be diagnosed from clear photographs and treated online. Early, minor bacterial problems, such as a slightly inflamed nail fold, can sometimes be managed online with close follow-up. Spreading bacterial infection, wounds, ulcers, and any foot infection in a person with diabetes need in-person care, and prescribing rules vary by country.
That honest split is the point of the consultation: feet hide serious trouble well, so the doctor's first job is sorting "annoying but safe" from "needs a clinic today", and the second is treating what genuinely can be treated from home.
How an online consultation helps with a foot infection
? Photograph in daylight: the whole foot from above, the sole, the skin between your toes (spread them with your fingers), and a close-up of any nail changes, redness or broken skin. If there is any spreading redness, draw around its edge with a pen and note the time. Our guide to photographing a skin problem for an online doctor shows exactly how.

itchy peeling between the toes and hot spreading redness are completely different problems. Photos plus a structured history usually separate them in one sitting.
antifungal creams do nothing for bacterial infection, and antibiotics do nothing for athlete's foot. Getting the label right saves weeks of the wrong tube.
close-up photos of nails and spread toes give the doctor the exact detail this diagnosis hangs on, plus a plan for stubborn fungal nails, which need patience and often testing.
diabetes, spreading redness, fever and dead-looking tissue are checked in every consultation, and when the answer is "clinic, today", you hear it clearly with directions, not a cream.
What the doctor checks in an online foot infection consultation
The assessment runs from danger signs down to detail. In a foot infection consultation, the doctor will typically assess:
- Diabetes, circulation and sensation, first and always: diabetes, known artery disease or numb feet reroute the whole consultation towards same-day in-person care, whatever the infection looks like.[1]
- Signs of spreading bacterial infection: expanding redness, heat, swelling, pain, red streaks up the leg, fever or feeling unwell, checked against your pen line and photos.
- The toe webs: the itchy, peeling, sometimes soggy white skin of athlete's foot lives between the fourth and fifth toes most of all, which is why the spread-toe photo matters.[3]
- The sole and pattern of scaling: fine dry scaling across the sole in a moccasin pattern points to a fungal cause that usually needs longer treatment.
- The nails: thickened, crumbly, yellow-brown nails suggest fungal nail infection, which is a months-long project and often needs confirmation before tablets.[2]
- Entry points and wounds: cracks between toes or on heels, blisters, cuts, puncture wounds, and ingrown nails with an inflamed fold, because these are where bacteria get in.
- Your background: immune-suppressing illness or medicines, poor circulation, swelling of the legs, and footwear, work and sport habits that keep feet damp.
- What you have tried: which creams, for how long, and whether treatment was continued after the skin looked better, the step most people skip.
Is it athlete's foot or a bacterial infection?
Athlete's foot is a fungal infection: it itches, peels and flakes, usually starts between the toes, often affects both feet, and grumbles along for weeks. Bacterial infection is different: one area becomes red, hot, swollen and genuinely painful, often spreading over hours to days, sometimes with fever. The first is uncomfortable; the second is urgent.
The two are also connected, which is why both get treated seriously. The cracks and soggy skin of untreated athlete's foot are a classic entry point for bacteria, turning a fungal nuisance into cellulitis, a spreading infection of the deeper skin that needs prompt antibiotics.[4] Athlete's foot itself belongs to the ringworm family of fungal infections, which our ringworm page covers across other body sites, and soggy redness deep in the toe webs can also be intertrigo, a moisture-fold rash with a fungal passenger. Naming the problem correctly is the whole first half of treating it.
Foot infections and diabetes: why the rules are different
If you have diabetes, any foot infection is urgent until proven otherwise. High glucose damages nerves, so injuries and infections can be painless and silently deep; it damages circulation, so healing is slow; and minor wounds can progress to ulcers, deep tissue infection or infection of the bone. Guidelines are unambiguous: a suspected diabetic foot infection needs urgent in-person assessment, and established pathways refer these feet to specialist multidisciplinary teams rather than treating them remotely.[1]
What that means on this page is simple, and we repeat it deliberately: we do not treat diabetic foot infections online. If you have diabetes and a new red, warm, swollen, discharging or broken area on your foot, arrange same-day in-person care; if you cannot reach your usual clinic, use an urgent-care service. What an online consultation can still do for people with diabetes is the surrounding work: prevention advice, daily foot-check technique, early review of athlete's foot before skin breaks (with a low threshold for in-person referral), and plain-language triage when you are unsure what you are looking at. Prevention is genuinely powerful here: daily foot inspection, well-fitting shoes, never walking barefoot, moisturising dry skin but not between the toes, prompt attention to corns and nails with a podiatrist, and treating fungal infections early, before they open the door.[1]
Which foot infection treatment might the doctor recommend?
Treatment follows the type of infection and your risk profile. This is the framework our doctors use, aligned with the cited guidance:[1][2][4]
Swipe sideways to compare →
| Presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Itchy, peeling skin between the toes (athlete's foot) | Topical antifungal for 1–4 weeks depending on the product, plus a strict drying routine | Usually yes | No better after two weeks of correct use, or skin breaks down and reddens |
| Dry scaling across the sole, or thickened crumbly nails | Assessment; nail infections usually need laboratory confirmation before months of oral treatment | Assessment yes; treatment case-dependent | Where local pathways require nail testing first, or scaling fails topical treatment |
| Red, swollen, tender skin fold beside a nail (early paronychia) | Warm soaks and antiseptic; antibiotics only with clear signs of bacterial infection | Often yes, with close follow-up | A collection of pus needs drainage; an ingrown nail that keeps recurring needs minor podiatry or surgery |
| Redness spreading up the foot or leg, heat, pain, fever | Same-day in-person care; antibiotics by mouth or into a vein after examination | No: we direct you the same day | Always |
| Any foot infection with diabetes, numbness or poor circulation | Same-day in-person care, every time | No | Always; diabetic foot infections can threaten the limb[1] |
Availability of individual medicines and who may prescribe them vary by country; your doctor confirms what applies where you are.

What you can do yourself
For athlete's foot without broken skin or diabetes, pharmacy antifungal creams such as terbinafine or clotrimazole work well: apply as directed for the full course (typically 1–4 weeks depending on the product) and continue a little beyond visible clearing, because stopping early is the usual reason it returns.[2][5] Dry carefully between the toes after every wash, change socks daily (cotton or wool over synthetics), alternate pairs of shoes so each dries out, wear flip-flops in shared showers and changing rooms, and use an antifungal powder or spray in shoes if sweating is heavy. Do not share towels, and dry your feet last or with their own towel so the fungus does not travel to your groin. If you have diabetes, skip self-treatment of anything beyond intact dry skin and involve a professional early.
Prescription treatment
A prescription is never issued without a consultation. After assessment, the doctor can prescribe stronger topical antifungals, or oral antifungal tablets for moccasin-pattern, recurrent or nail disease, after checking your other medicines and liver health, and usually after laboratory confirmation for nails, which local pathways often require.[2] Antibiotics are reserved for genuinely bacterial infections: that is antibiotic stewardship, and it also protects you from side effects that will not buy you anything. Early, minor bacterial infections suitable for oral antibiotics at home come with a pen-line tracking plan and a fixed review; anything spreading or systemic is redirected to in-person care the same day.[4]
When we treat a foot infection online, and when we refer you
We treat online: athlete's foot, including recurrent cases and the drying routines that stop the cycle; fungal nail assessment, with the honest testing-first pathway explained; early minor nail-fold infections with close follow-up; and reviews when treatment is not working on schedule.
We refer or redirect you: every foot infection in someone with diabetes, numbness or poor circulation, the same day, without exception; spreading redness, fever or red streaks, the same day; ulcers, deep or dirty wounds, puncture wounds through shoes, and suspected foreign bodies; abscesses and pus collections that need drainage; ingrown nails needing minor surgery; and any foot that is suddenly cold, pale or blue, which is a circulation emergency. When we redirect you, you leave knowing exactly where to go and how urgently.
When to get in-person care
Diabetes plus any foot infection means same-day in-person care, every time. For anyone: same-day care for redness spreading up the foot or leg, fever with a painful hot foot, a deep or smelly wound, or pus you cannot drain. Call 112 immediately for signs of sepsis (high fever with confusion, rapid breathing, a racing heart or mottled skin), for skin turning grey, purple or black, for pain wildly out of proportion to what you can see, or for a foot that is suddenly cold, pale and painful.

Frequently asked questions about a foot infection
Can an online doctor prescribe treatment for a foot infection in Europe?
Yes, for the right cases, and only after a consultation. A prescription is never issued without one: the doctor assesses your photos and history by video first, then prescribes antifungal treatment for athlete’s foot or fungal nails, or antibiotics for carefully selected minor bacterial infections. Spreading infections and all diabetic foot infections are referred to in-person care instead. Prescriptions can be sent to a pharmacy near you in most EU countries, and your doctor confirms what applies in your country.
How much does a foot infection consultation cost?
A video consultation costs €47. The exact price is shown before payment, and there is no subscription. If the doctor can’t treat you online, you get a full refund and clear directions to the right care.
How quickly can a doctor look at my foot?
Appointments are available daily from 7am to 11pm, often the same day. Upload photos of the whole foot, the sole, between your toes and any nails involved before the call. If redness is spreading or you have diabetes, do not wait for an appointment: seek in-person care the same day.
I have diabetes and my toe is red. Can I book an online consultation?
No: please get in-person care the same day. In diabetes, a red, warm, swollen or broken area on the foot can be the surface of a much deeper problem, because nerve damage hides pain and poor circulation slows healing. Diabetic foot infections can threaten the limb and need physical examination urgently. If you cannot reach your usual clinic today, use an urgent-care service.
How do I tell athlete’s foot from a bacterial infection?
Athlete’s foot itches, peels and flakes, usually between the toes and often on both feet, and it changes slowly. Bacterial infection hurts more than it itches: one area turns red, hot and swollen, spreads over hours to days, and can bring fever. Itchy and flaky suits an online consultation; hot, spreading and painful needs in-person care.
Do I need antibiotics for athlete’s foot?
No. Athlete’s foot is a fungal infection, and antibiotics do nothing against fungi; the treatment is an antifungal cream used for the full course, plus keeping the feet dry. Antibiotics only enter the picture if broken skin lets bacteria in and the area becomes hot, painful and spreading, which is a different problem.
Why do my feet keep getting infected?
Usually because the conditions that caused the first infection never changed: damp shoes, sweaty socks, shared showers, untreated fungal nails reseeding the skin, or stopping treatment as soon as the itch faded. A recurrence consultation looks for the loop and breaks it: full-length treatment, shoe and sock routines, and testing nails when they are the reservoir.
