I have been having chest pains for over a week now. Two years ago I went into the hospital for chest pain and headache that I had over a week, and was diagnosed with high blood pressure and I was almost in stroke level. I now take blood pressure medicine. But lately my chest has been hurting and my heart seems to be jumping all the time and my head doesn't feel right. Have had heart tests/stress tests done before and was told everything was ok. A while back I was told I had an irregular heartbeat and enlarged heart. Dont have too much confidence in doctors because of too many different diagnoses. Why does my heart hurt and jumps?
