Hello, a couple days ago I suffered a blunt trauma injury to the groin area while mountain biking. Ever since, I have had a sharp/burning pain in my groin area whenever I sit up from a lying position, as if a hot wire is being pressed into my skin. I do not suspect the injured structure to be the groin tendon itself, as I have no pain when walking, jumping, etc. The pain is only present when I sit up or raise my legs from a lying position. What might the source of this pain be? Will it heal on its own, or will medical intervention be necessary? Thanks.
