I'm Ready to Give Up!!!

I've been having pain and severe burning in the upper part of my stomach, just below the breast area. I cannot bear to have anything around my waist. Can't wear a bra because it fits right over the area that's bothering me. Almost everything I eat causes pain. I've pleaded with my doctor to find out what is going on. So far i've had an upper gi, and endoscopy, and a gall bladder test. Have not had a hida scan but after reading the post on this board I will request one tomorrow. My neighbor is a doctor (not my personal physician) and he told me regular gall bladder tests are rarely accurate. At this time, my doctor is treating me for h pylori though my blood test was negative. I'm on two high powered antibiotics, nexium and pepto bismol. I've been on this treatment for six days now and can tell no difference. I'd really like to hear from someone who might have had similar symptoms. I've seen posts that described the pain in upper stomach but few who mentioned the terrible burning (as if my stomach is on fire).
Somebody please let me know something as i'm getting so frustrated and so out of heart.
