Paronychia: Bacterial Nail-Fold Infection

Bacteria can enter through a hangnail, cracked skin, nail biting, manicure trauma, or an ingrown nail edge. The infection usually begins at one side of the nail fold and may become a tense, painful pocket. The nail itself can remain intact while the surrounding skin becomes inflamed. Persistent dampness or repeated irritation can contribute to a longer-lasting problem, sometimes involving yeast as well.

Wash gently, dry thoroughly, and avoid biting, cutting, or picking the nail fold. Do not share nail tools or use someone else’s medication. A clinician may select a topical or oral treatment based on the examination; Antibiotics For Skin Infection explains the treatment category. If pus is trapped, medicine alone may not release the pressure and Abscess Drainage may be considered.

Get medical help promptly if redness is spreading, pain is escalating, pus is collecting, fever develops, red streaks appear, or movement becomes difficult. Do not delay assessment for an infection near the thumb pad or a finger joint. People with diabetes, circulation problems, or immune suppression should seek advice early, even when the visible area seems small.

Ask what features support bacterial infection, whether a sample or drainage is needed, how long to use the prescribed treatment, and how to prevent another break in the nail-fold skin.
