An infected ingrown toenail produces a distinct set of signs that go beyond the normal discomfort of a nail pressing into skin. The key difference is drainage: if you see liquid or pus coming from the area around your toenail, the tissue is almost certainly infected. Other hallmarks include increasing redness or skin darkening, swelling that gets worse rather than better, and the toe feeling noticeably warm or hot to the touch.
Normal Irritation vs. Infection
Not every ingrown toenail is infected. In the earliest stage, you’ll notice redness and mild swelling along the nail fold, with tenderness when you press on it or when shoes put pressure on the toe. This is inflammation, not infection. Your body is reacting to a nail edge digging into soft tissue, but bacteria haven’t taken hold yet.
Infection develops when bacteria enter the broken skin around the nail. The signs shift noticeably:
- Pus or cloudy drainage leaking from the side of the nail, sometimes with a foul smell
- Throbbing pain that persists even when you’re not touching the toe or wearing shoes
- Increased warmth in the toe compared to your other toes
- Worsening redness that spreads beyond the immediate nail fold
- Skin growing over the nail edge, which traps bacteria underneath
Clinicians grade ingrown toenails on a three-stage scale. Stage one is mild: just redness and inflammatory swelling. Stage two is moderate, where you start seeing discharge from the area. Stage three is severe, marked by the formation of granulation tissue (a small, raw, beefy-red bump that bleeds easily), abscess formation, or chronic thickening of the skin along the nail fold. If you see that red, fleshy bump next to your nail, you’ve moved well past simple irritation.
When the Infection Is Spreading
A localized infection stays around the nail fold. A spreading infection is a different situation. Watch for redness that extends beyond the toe into the surrounding foot, or red streaks moving away from the toe toward your ankle. These are signs of cellulitis, a bacterial skin infection that has moved into deeper tissue.
Systemic symptoms raise the urgency further. Fever above 100.4°F, chills, fatigue, or swollen lymph nodes (you might feel tender lumps in your groin on the affected side) all suggest the infection is no longer contained to your toe. This needs prompt medical attention, not home soaking.
Why Diabetes and Circulation Problems Change the Equation
If you have diabetes or poor circulation in your feet, treat any ingrown toenail as potentially serious from the start. Poor circulation slows healing and weakens your foot’s ability to fight off infection. In people with diabetes, even small cuts and open sores around the nail can escalate into deep infections that threaten the toe or foot. The American Diabetes Association specifically warns against cutting into the corners of toenails, since this is one of the most common triggers for ingrown nails. If you have diabetes and suspect your ingrown toenail is infected, skip home remedies and see a podiatrist or your doctor quickly.
What You Can Do at Home
For a mild ingrown toenail that shows irritation but no signs of infection (no pus, no spreading redness, no warmth), warm soaks can help. Mix one to two tablespoons of unscented Epsom salts into one quart of warm water and soak your foot for 15 minutes. Do this several times a day for the first few days. After soaking, you can apply a topical antibiotic ointment to the area and cover it with a clean bandage.
Wear open-toed shoes or shoes with a wide toe box while the area is inflamed. Avoid picking at the nail or trying to dig it out, which introduces more bacteria. If you don’t see improvement within two to three days, or if pus appears, the nail likely needs professional care.
What Happens If You Need a Procedure
The most common treatment for a persistently ingrown or infected toenail is partial nail removal, where a clinician numbs the toe and removes the strip of nail that’s digging into the skin. It sounds worse than it is. The numbing injection is the most uncomfortable part, and most people return to work or school the next day.
After removal, healing takes about six to eight weeks for a partial removal and eight to ten weeks if the entire nail is taken out. You’ll need to redress the wound every other day until it’s fully healed, and you should avoid swimming and intense exercise during that window.
Recurrence is the main concern. When the nail removal is paired with a chemical treatment to the nail root (preventing that strip from regrowing), recurrence drops dramatically. One clinical trial of 140 patients found recurrence in only 1.4% of those who had the chemical treatment, compared to 10% of those who had nail removal alone. For younger patients under 35, the chemical treatment brought recurrence to zero. Without it, nearly 15% of younger patients saw the problem return.
That Red Bump on Your Nail Fold
A chronic ingrown toenail sometimes produces a small, red, rapidly growing bump next to the nail that bleeds easily when touched. This is called a pyogenic granuloma, and while it looks alarming, it’s a known complication of prolonged nail irritation. It forms as an exaggerated healing response to the nail spicule embedded in the skin. In children, it’s frequently tied to nail biting or improper trimming.
These bumps are worth getting checked. A single granuloma on the nail bed occasionally needs a biopsy to rule out other growths, including rare skin cancers that can mimic its appearance. If you’ve had a red, bleeding bump near your toenail for more than a couple of weeks, have it evaluated rather than assuming it will resolve on its own.
