burning and tight under breasts

I have gerd and have been on various ppi for over a year. Everything got better after I had my gallbladder out. Dr. said I had gallbladder disease . Then the burning, tight , heavy feeling came back. It's not 24/7, but it is daily and it really hurts.. Dr did a upper gi and said that there was red inflammation. and didn't give me any new meds to take. I contacted him a few weeks later and said how bad it was bothering me. He put me on a sulper med. you take 4 times a day for 2 weeks. After the 2 weeks were up I asked If I could continue as I thought it might be helping. Now I don't think it is. Would the burning tight feeling I get be caused from inflammation?? It goes all the way from left to right, but the most pain is in the center. I have a lot of nerve problems and I'm not sure it isn't that.
Have any of you had anything like this..??
