Paronychia is a medical term that refers to an infection of the skin surrounding a fingernail or toenail, which can be acute or chronic. It is typically caused by bacteria, fungi, or other microorganisms and may result in redness, swelling, and pain around the affected nail. In severe cases, pus may also develop, and the nail may become deformed or discolored. Treatment for paronychia may involve antibiotics or antifungal medications, warm soaks, and in some cases, surgical drainage of the infected area.
