Paronychia is a bacterial infection that requires enhanced cleaning of the nail groove and administration of anti-infection symptomatic treatment. Rest, a light diet, and nutritional support are important. Oral or intravenous antibiotics should be used, with cephalosporins recommended. Additionally, combating anaerobic bacteria is necessary. This can be coordinated with surgical dressing changes and local treatment. Iodine disinfection may be employed, and incision and drainage may be necessary to promote pus discharge. Ichthyol ointment may also be used to help draw out the pus. During treatment, increased water intake and improved cleanliness and care of the nail groove are recommended, along with avoiding dirty water to aid recovery.
