What should you know about paronychia after draining?

Drainage releases trapped fluid from the infected nail fold, but tenderness, mild swelling, and a small open area can remain while the tissue heals. The nail may stay ridged or grow unevenly because inflammation can affect the nail-producing area; improvement in the surrounding skin does not always change the nail immediately.

A clinician may decide that drainage is enough, or may prescribe treatment when infection remains, spreads, or has a particular cause. Recurrent or long-lasting inflammation can involve irritation, biting, picking, or a [Skin Yeast Infection](/conditions/cutaneous-candidiasis/), so repeated self-drainage is unsafe.

Follow the dressing and bathing instructions you were given. Wash your hands before touching the area, keep the dressing clean and dry as directed, and avoid squeezing, cutting the cuticle, biting the nail, or sharing nail tools. Protect the finger or toe from repeated wet work, chemicals, and friction while it is tender.

Take prescribed medicine exactly as instructed; do not use leftover tablets or stop early without advice. [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/) may be considered when a clinician finds a bacterial infection, while [Abscess Drainage](/treatments/minor-procedures/abscess-drainage/) explains the procedure context. Attend any planned wound check.

Contact the clinic if pain or swelling is increasing, drainage becomes foul-smelling, pus returns, the wound will not stay covered, or the redness moves along the finger or toe. Seek urgent care for fever, feeling very unwell, rapidly spreading redness, severe throbbing pain, numbness, or difficulty moving the digit. People with diabetes or reduced immunity should use a lower threshold for review.

Ask how to change the dressing, when the wound may get wet, and whether you need a follow-up check. Clarify which pain relief is suitable, whether medicine is needed, how to protect the nail as it grows, and which changes mean the infection may be returning.
