I seem to have the symptoms of angina. I get discomfort in the top left portion of my abdomen. This discomfort occurs sometimes at rest. Ive had an EKG during rest and it was normal. What boggles me about this is that during very high heart exertion I rarely get it. Additionally, sometimes I dont have it for weeks at a time. It may be related to stress… But I dont see why stress would cause it but excercise would not. Any ideas?
