I am 36yr old mother of 4. I have been going to my PCP and cardiologist for a few months now trying to figure out what's going on. I get these little squeezing chest pains, near left breast a few inches below clavicle. That's been off and on for years but sometimes more frequent. Also get pinching in left arm, a little below shoulder. About 3wks ago, I got this pain in/around my left shoulder blade and it comes back off and on. I have done a treadmill stress test without nuclear, multiple EKGs, chest xray, blood work...all show a healthy heart. My Bp stays about 118/70. My cardiologist swears this is not heart related. Anyone else experience this? I'm scared....any ideas?
