So lately I'll start feeling pain and tightness in my chest, neck and arms. Then it feels like I can't breathe but my oxygen is fine. Everytime something feels wrong I begin to panic. I never used to be this way but lately it's gotten worse. After getting a EKG and amongst other tests the doctors say I'm in perfect health and it's just anxiety tricking me. So I would like to know how you all handle it. Any advice helps.
