Bacterial paronychia treatment

Warm-water soaks can ease an early, mild nail-fold infection. A visible pocket of pus may need drainage by a trained clinician rather than squeezing or piercing at home.

Bacteria can enter through a torn cuticle, hangnail, bite, manicure injury or ingrown nail edge. The surrounding fold becomes red, swollen and tender; pus may collect beside or beneath the nail.

A sudden painful episode is often managed differently from swelling that persists or repeatedly affects several nails. Long-lasting paronychia may involve ongoing wet work, irritants, inflammation or yeast, so repeated antibiotics are not automatically appropriate.

For a mild early episode, soak the digit in comfortably warm water, dry it thoroughly, and protect it from biting, picking and wet work. Remove rings from a swelling finger before they become tight. Keep the nail short but do not cut into the inflamed fold.

A clinician decides whether topical or oral antibiotics are useful. When pus is trapped, making a small opening to drain it can relieve pressure and treat the source. Do not attempt drainage with a needle, and take any prescribed medicine exactly as directed.

Seek prompt care if pain or swelling is rapidly increasing, redness spreads along the finger or toe, movement becomes difficult, pus collects, or you develop fever or feel unwell. Severe throbbing beneath the nail also needs assessment.

Get earlier help if you have diabetes, poor circulation or reduced immunity. Recurrent inflammation, nail distortion, several affected nails or symptoms lasting beyond an acute episode merit review for irritant exposure, chronic inflammation or fungal involvement.

Ask whether there is a drainable collection, whether antibiotics add benefit, and how to dress the area after treatment. Mention nail biting, recent salon work, ingrown nails and frequent water or chemical exposure because these details can change prevention advice.
