I Have Been Suffering From A Serious Pain In The

I have been suffering from a serious pain in the middle of my chest. It is painful to eat. There is a lot of burping. I went to the hospital on Thursday and they did a heart catheter and everything was fine and they sent me home. I went back to the emergency room on Saturday because of the pain and trouble breathing -- they did a CT scan and said there was no blood clots in my lungs and sent me home. I am still in tremendous pain and don't know what to do.
