I m a 25 year old female. 5 8 and 250 lbs. I have been having chest pains on and off for about two years. It comes and goes, but everytimes it starts back, something else hurts too. Now its my chest, jaws, back, neck. I went to a cardiologist about a year ago; had a normal ultrasound. Every now and then my heart feels like it skipps a beat. No one has been able to tell me what is wrong. (This all started before I gained ~60 lbs). It is a dull, achy pain in the center, and left side of my chest. Dull pain in left shoulder blade. Tingling pain in jaws. Should I still suspect my heart? What else could it be?
