A couple of weeks ago, I was awakened by a coughing spell, (I have GERD and am a smoker) and there was this very painful burning in my right groin/upper thigh area. The burning went away, at first, but now every time I cough, sneeze, or even blow my nose it really hurts there, and the burning sensation is staying there now. I am currently undergoing physical therapy for sciatica in my left leg, and my PT said this sounded like a pulled muscle. Can you help me figure out what's going on and how to treat it?
