Paronychia from a hangnail

A hangnail is a small torn piece of skin at the side of the nail. Pulling it can enlarge the tear and leave an entry point for germs. Paronychia may then cause redness, swelling, warmth, and tenderness along one side of the nail. Fluid or pus may collect beneath the raised skin. The hangnail itself is not proof of infection; the surrounding changes and the course of symptoms matter.

Wash your hands, soften the hangnail with warm water, and trim only the loose edge with clean nail tools rather than tearing it. Keep the area dry afterward and cover it if friction makes it sore. Avoid chewing the skin, cutting the cuticle, or squeezing swelling. If infection is present, a clinician may prescribe Antibiotics For Skin Infection. A trapped collection may require Abscess Drainage, while repeated moisture-related inflammation may be linked with Skin Yeast Infection.

Arrange care when pain or swelling continues to increase, pus appears, the redness spreads, or the nail begins to lift or change. Seek urgent assessment for fever, red lines extending up the finger or hand, severe swelling, or difficulty bending the finger. Early advice is sensible if you have diabetes, circulation problems, or an immune condition.

Ask whether the torn skin needs treatment, whether pus has collected, how to trim future hangnails safely, and which warning signs mean the infection needs review.
