Quick answer. An ingrown toenail occurs when the edge of the nail grows into the surrounding skin, causing pain, redness and sometimes infection. Mild cases can be managed at home, but spreading infection, or any ingrown toenail in a person with diabetes, needs prompt medical attention.
An ingrown toenail happens when the edge of a nail, most often the big toe, digs into the surrounding skin. It is a common and painful problem in Singapore, often blamed on tight shoes and incorrect nail trimming. What begins as mild tenderness can progress to redness, swelling and infection if left unattended.
This guide explains what an ingrown toenail is, why it develops, how to care for it at home, and when professional treatment such as a minor procedure is needed. It also highlights why people with diabetes should be especially cautious. This is general information and does not replace advice from a doctor or podiatrist.
At a glance
| Stage | Signs | What to do |
|---|---|---|
| Mild | Tenderness, slight redness at nail edge | Warm soaks, proper footwear, gentle care |
| Moderate | More pain, swelling, some discharge | See a doctor; may need treatment |
| Infected | Pus, spreading redness, increasing pain | See a doctor promptly; antibiotics may be needed |
| Recurrent | Keeps coming back | Consider minor surgery (partial nail removal) |
| Diabetic / poor circulation | Any of the above | See a doctor promptly, even if mild |
What is an ingrown toenail?
An ingrown toenail occurs when the side or corner of a nail grows into the soft skin beside it rather than over the top. This irritates the skin, causing pain, redness and swelling, and can allow bacteria in, leading to infection. The big toe is by far the most commonly affected.
Ingrown toenails are very common and affect people of all ages. Most mild cases can be eased at home, but they have a tendency to recur, and some need a minor procedure to resolve them permanently. They can become more serious in people with diabetes or poor circulation.
Symptoms & signs
The typical symptoms of an ingrown toenail include:
- Pain and tenderness along one or both sides of the nail
- Redness and swelling of the surrounding skin
- Pain when wearing shoes or when the toe is pressed
- Fluid, pus or bleeding if the area becomes infected
- Overgrown skin or tissue beside the nail in longer-standing cases
Causes & risk factors
Several factors make an ingrown toenail more likely:
- Cutting nails too short or rounding the corners rather than cutting straight across
- Tight, narrow or ill-fitting shoes that press on the toes
- Injury to the toe, such as stubbing or repeated pressure from sport
- Naturally curved or thick nails
- Sweaty feet and poor foot hygiene
- Diabetes or poor circulation, which raise the risk of complications
How it's diagnosed
An ingrown toenail is usually diagnosed by simply looking at the toe, as the appearance is characteristic. A doctor will assess how far the nail has grown into the skin and whether there are signs of infection, such as pus, spreading redness or warmth.
If you have diabetes or poor circulation, the doctor will examine the foot more carefully and check sensation and blood flow, because these conditions raise the risk of infection spreading and of slow healing. In recurrent or complicated cases, the doctor will discuss longer-term options.
Treatment & home care
Mild ingrown toenails can often be managed at home:
- Warm soaks: soak the foot in warm water several times a day to soften the skin and reduce discomfort
- Footwear: wear roomy, comfortable shoes or open-toed footwear while it heals
- Gentle care: keep the area clean and dry; do not dig out the nail yourself
- Pain relief: simple painkillers if needed
If the toenail is infected, recurrent or not improving, a doctor or podiatrist may prescribe antibiotics or perform a minor procedure. The most effective long-term treatment is partial nail avulsion, in which the offending edge of the nail is removed under local anaesthetic, sometimes with a chemical applied to stop that part of the nail regrowing. Avoid attempting bathroom surgery yourself, which often makes things worse.
When to see a doctor & which specialist
See a doctor or podiatrist if home care does not help within a few days, if the pain is severe, or if there are signs of infection. Seek medical attention promptly if you have:
- Spreading redness, increasing pain, warmth or pus around the toe
- A fever or feeling generally unwell
- Repeated ingrown toenails that keep coming back
If you have diabetes or poor circulation, see a doctor promptly for any ingrown toenail, even a mild one. In diabetes, foot infections can progress quickly and heal poorly, so early care is essential. If you develop a rapidly spreading infection, red streaks up the foot or leg, or feel very unwell with fever, call 995 or go to A&E. For assessment, treatment and minor procedures, start with a GP clinic in Singapore, who can refer you on if needed.
How to prevent ingrown toenails
Because ingrown toenails tend to recur, prevention is as important as treatment. A few simple habits lower the risk:
- Cut your toenails straight across rather than rounding the corners, and avoid cutting them too short.
- Wear roomy, well-fitting shoes that do not press on your toes, and rotate sports footwear.
- Keep your feet clean and dry, and change damp socks promptly.
- Protect your toes during sport and avoid picking at the nail edges.
What to expect at the appointment
The diagnosis is usually clear from looking at the toe. If a minor procedure such as partial nail avulsion is needed, the doctor numbs the toe with local anaesthetic, removes the offending edge of the nail, and may apply a chemical to stop that part of the nail regrowing. The toe is then dressed, and you will be given advice on keeping it clean while it heals over the following weeks.
Costs and subsidies in Singapore
For consultation and basic care at a participating GP clinic, eligible Singaporeans may receive a subsidy under the Community Health Assist Scheme (CHAS). Note that subsidies and MediSave generally apply to consultations and certain treatments rather than every minor procedure, so it is best to check what is covered with the clinic beforehand. People with diabetes or poor circulation should seek care promptly for any ingrown toenail, even a mild one, as foot infections can progress quickly.
Common questions
Can I treat an ingrown toenail myself?
Mild cases can often be eased with warm soaks, roomy footwear and gentle care. Avoid digging out the nail yourself, which usually makes things worse and risks infection.
Will it come back after a procedure?
Partial nail avulsion with a chemical to prevent regrowth of that edge has a good long-term success rate, especially when combined with correct nail-cutting and well-fitting shoes.
