I have chest pressure, like a ton of bricks on my chest, shortness of breath, weakness, and now my right arm is tingling numb. Also arythemia. Months ago I went to the hospital and they said I didn t have a heart attack. A cardiologist follow up did a holter monitor and did not find anything. My symptoms are worse. Excericse is tough, I have to rest everyday because of the chest pain and weakness and dizziness. Should I go to another hospital and Doctor?
