What Causes Chest Pain, Dizziness And Back Pain?

Hi there, last month I had an episode whereby I had chest pain, dizziness, cold sweat, and shoulder and back pain. I felt like I was having a heart attack. A couple of weeks later I had crushing chest pains followed with acute onset of vomitting shortness of breath and cold sweats. I saw a doctor who since diagnosed this as indigestion, it didnt feel that way. Blood tests were inconclusive and since then I have had a dull chest ache which worsens when I bend over, any ideas pls ?
