So I htought I was doing much better and have been feeling much better. Until last night. I had a horrible nights sleep and have not been feeling good all day. Pain in the middle of my chest, burning in the middle of my back, sore left shoulder and soreness in my chest. I was so bad I ended up at the ER. They did EKG and blood test and said I am fine. The doctor thinks I have costochondritis. Does anyone else get these symptoms? Pains in the chest, sore left shoulder? pain the back? Its very scary and makes you feel like you are having a heart attack. I have had all the heart tests done and all are good. 30 day heart monitor, several EKG's and an ultra sound of my heart. I ate mexican food for lunch yesterday which I think was the big mistake
