Answer

Physical findings in acute paronychia include the following:

  • The affected area often appears erythematous and swollen

  • In more advanced cases, pus may collect under the skin of the lateral fold

  • If untreated, the infection can extend into the eponychium, in which case it is called eponychia

Further extension of the infection can lead to the involvement of both lateral folds as it tracks under the nail sulcus; this progression is called a runaround infection
