Persistent hangnails should be evaluated by a physician.[4] Complications{{main article|Paronychia}}Hangnails can become infected and cause paronychia, a type of skin infection that occurs around the nails. Treatments for paronychia vary with severity, but may include soaking in hot salty water, the use of oral antibiotic medication, or clinical lancing. Paronychia itself rarely results in further complications but can lead to abscess, permanent changes to the shape of the nail, or the spread of infection.[5] References1. ^Hangnail, The Free Dictionary Nagel (Anatomie)#Niednagel{{injury-stub}}2. ^Treating a Hangnail - Topic Overview, WebMD 3. ^{{cite book|author1=Thomas P.
