In medicine, paronychia (/ˌpærəˈnɪkiə/; Greek: παρονυχία: para-, around, onukh-, nail) is a nail disease that is an often-tender bacterial or fungal infection of the hand or foot where the nail and skin meet at the side or the base of a finger or toenail. The infection can start suddenly (acute paronychia) or gradually (chronic paronychia). Paronychia is commonly misapplied as a synonym for whitlow or felon.Source: Wikipedia
