Hi i am 24 year old male who just quit smoking 4 months ago. I eat very healthy for my age , i take 1 and a half grams of cod liver oil daily for the past year, and i dont eat red meat. I jog about 3 times a week for about 20 minutes a time.4 months ago i started getting a series of major panic attacks, with health anxiety and lightheadedness almost all the time. i have done 2 ekgs in the past 4 months, blood tests chest xray to find out if there was an underlying medical problem. The thing that makes me think i have heart problems is i have been having pain in my left arm, armypit area pain, back pain shoulder pain for quite a long time. Is it possible that 2 ekgs could have missed a major heart problem or maybe my heart problem has just surfaced now? i have no family history of any heart problems at all.
