Age: 44, 5'7" 180lbs I've had these symptoms for 9 days now. ER has determined that I not having heart attack, stroke, or any of the common scary things they test for. Left arm aches off and on, loud ringing left ear varies, pain behind left eye varies, blood pressure higher than normal, easily winded now going up stairs, left thigh feels funny, and certain times it feels like my heart is being squeezed and feels like I'm not going to make it. I've been to the ER twice, doctor's office twice. All test results are negative. I'm frustrated and scared when the attacks happen. I caught a bad cold while traveling to Salt Lake City. The cold symptoms went away. I went for a short jog when my left arm started hurting and I got dizzy. Heart/chest pressure started 3 days later. Again, this isn't a heart attack. I'm an healthy guy. Any suggestions would be really helpful.
