<s>[INST] Hello, Im a 31 year old male. Last week I had a full blood panel work done and everything came back better than normal. Tonight I think I may have had a minor heart attack. My back locked up, I couldnt breathe and I was sweating hard for about 10-15 minutes. I took tylonol for the sweats and advil for the back. I still have some discomfort in my chest when i can breathe deep, but the pain is gone now. All this back pain seemed to start on my left shoulder and worked its way down to my lower back and into my chest. Whats happening to me? [/INST] Hello! Welcome on Chat Doctor! Your symptoms do not seem to be related to any heart disorder (including a heart attack). The fact that your symptoms are triggered by deep breathing, could indicate possible musculoskeletal pain. For this reason, I would recommend taking ibuprofen or acetaminophen for the pain. Your situation will improve in the next days. There is nothing to worry about! Kind regards,  </s>
