I have pain in my chest when I exercise - such as walking on a treadmill. It is always in the same spot, and it is a gripping, squeezing pain. (Not center chest, but left side mostly.) When the pain starts, it is much worse when I try to inhale. It is relieved when I slow down or stop - but not immediately. I have had a test (forgot the name) 2 years ago and Dr. said I have tricuspid regurg, but this should not be causing the pain. She said all things looked clear but to check it again in a year. The pain is predictable. When I exercise and get my heart rate up this pain grips my chest and I can hardly catch my breath. The pain happens sometimes at rest, but not as bad. What kind of test should I have?
