I have been having chest tightness with numbness in left arm, back pain, and lots of other symptoms that something is going on with my heart, circulatino, etc. Doctors ran blood test, did an EKG, but nothing showed up. Doctor put me on betablocker, which is helping, but still having pain/tightness and other symptoms. Doctors are dismissing me because of age (33) and normal blood tests. They say it is stress. The tightness I feel usually comes on with activity or stimulation (smoking, caffeine) and is more like angina. My doctor hasn't given me a stress test yet, is making me wait two months, and gave me a prescription for anxiety meds. Two months ago I was healthy. I was able to run four miles a few times a week. Now I can barely walk across the room without chest pain and other pains. I'm worries there is something more to my pain, possible heart problem, circulation problem. And I'm frustrtated my doctor won't take me seriously.
