I am being treated for hyperthyroid. I started getting some really low pain below the sternum bone upper stomach. I get a lot of gurgle noise and can feel it drop down, and then the pain goes away. Sometimes I can feel a sharp pain under the sternum. Comes and gos quickly. The other sharp pains I feel are not radiating but I get sharp pain just over the right nipple, not deep pain but like a pinch. Also just on the front side of my armpit right side. Little pains here and there on arms. I dont know what to make of some of this. Never any pain on exertion but only at rest. My recent blood work on cholestral the Dr. said was good. I am 60. Had heart cath 10 years ago and all was great. Dont smoke, drink, not overweight.
