What Should You Know About Paronychia Toe?

Paronychia of the toe is inflammation or infection in the skin fold beside a toenail, often causing tenderness, redness, swelling, or drainage. It can start after a cuticle is picked, the nail is trimmed too closely, footwear rubs the skin, or an ingrown nail breaks the nail fold. Acute cases can develop quickly; ongoing irritation or repeated wetness can contribute to a longer-lasting form.

The nail fold is the rim of skin that borders the nail. When this barrier is damaged, bacteria or yeast can enter and trigger inflammation. The area may feel warm and sore, and a pocket of pus can form beside the nail. A yeast-related problem may be more persistent and can affect more than one nail fold, especially when the area stays damp. Read about [Skin Yeast Infection](/conditions/cutaneous-candidiasis/) if your clinician suspects that cause.

Paronychia is not the same as an infection deep under the nail or in the toe bone. A clinician may examine the nail edge, surrounding skin, and any drainage to distinguish these problems and to look for an ingrown toenail or another source of pressure.

Keep the toe clean and dry, and avoid cutting, biting, or pushing back the cuticle. Wear shoes with enough room around the toes, change damp socks, and avoid squeezing a swollen area. Warm water soaks may soothe tenderness for a short period; dry the toe carefully afterward. Do not pierce or drain the area yourself, because this can drive infection deeper or create another wound.

A healthcare professional may recommend a topical treatment, prescribe antibiotics when a bacterial infection is suspected, or release a trapped collection of pus. Antibiotics are not suitable for every cause, so do not use leftover medicine. For more information, see [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/). If an abscess has formed, [Abscess Drainage](/treatments/minor-procedures/abscess-drainage/) may be considered by a trained clinician.

Arrange medical assessment if redness or swelling is spreading, pain is becoming stronger, pus is collecting, or the nail is lifting or changing shape. Seek prompt care if you develop fever, red streaks moving up the foot, marked swelling, numbness, or difficulty walking. People with diabetes, poor circulation, reduced sensation, or a weakened immune system should contact a clinician early because a small toe wound can need closer monitoring.

If symptoms keep returning, an ingrown nail, repeated friction, eczema, or yeast may be maintaining the problem. A clinician can address that trigger instead of treating each flare in isolation.

Ask whether the nail edge is ingrown, whether drainage should be tested, and which signs would mean the infection is spreading. You can also ask how to trim the toenail while the fold heals and whether your footwear or another skin condition could be contributing.
