Do you trim your cuticles? If you trim or even push back your cuticles you are at risk of developing an infection around the skin of the nail, called a Paronychia. Paronychia is fairly common. It is caused by injury to the skin around the nail, such as biting off or picking a hangnail or trimming or pushing back a cuticle. If you develop any signs of redness, drainage or tenderness on the skin around the nail, seek medical care immediately. You may require antibiotics for a possible infection.
