Hi, im a 33 year old femal. Over the last month ive been having on and off chest pain accompanied by what feels like heart burn, dizziness, shortness of breath, pain on left side of my neck, irregular heart rate ranging from 72-187bpm, ice cold feeling on the left side of my entire body, tingling in my head and am extremely exausted. EKG, xray and eco cardio gram came back normal. Blood tests had elevated enzimes but they did not find a blood clot in my chest with the CT scan. Should i be worried? I dont drink, im not over weight, im very active and dont take any medication. I have always been very healthy till now. Please help
