question: I have been experiencing left sided chest pressure/pressure in the left armpit area. I have already gone to a hospital and had an EKG, chest x ray, blood test, etc. They all came back negative, I have no heart defects, supposedly, nor do I have anxiety. I am not overweight, I dont have high blood pressure, the only health risk I can think of is that I have a high fat diet. So, what could be the source of this left sided pressure?
