Is paronychia dangerous?

The infection starts in the skin fold beside the nail, sometimes after a torn cuticle, biting, manicure injury, or repeated exposure to water and irritants. A pocket of pus can form and create throbbing tenderness. In people with diabetes, poor circulation, or reduced immune function, a small finger infection deserves earlier review because healing may be less reliable. A yeast-related cause can also produce persistent swelling around the nail; see Skin Yeast Infection for related information.

Keep the area clean and dry, avoid cutting or squeezing the nail fold, and protect it from further trauma. A clinician may recommend Antibiotics For Skin Infection when bacteria are suspected. If a clear pus pocket is present, Abscess Drainage may be needed; do not pierce it yourself.

Arrange prompt care if redness is spreading, pain is increasing, pus is accumulating, the fingertip becomes difficult to move, or you feel feverish or unwell. Seek urgent help for red streaking up the finger or hand, marked swelling, numbness, or severe pain.

Ask whether the infection looks bacterial, yeast-related, or abscessed; whether drainage is needed; and which changes should trigger same-day review.
