I have a small, pinkish bump at the base of the penile shaft following an ingrown hair. It has gotten smaller since I resolved the ingrown hair, and is now a little smaller than a pencil eraser, however, it has not seemed to change over the past week, and it looks/feels almost like a ball of scar tissue. After resolving the ingrwon hair myself, I have been applying Mederma scar gel once daily. Is this something that will resolve itself, or is it a cyst that needs medical attention to be removed?
