I m a 54 year old white male 5 10.5 and 225 lbs. I don t drink or do drugs. When I lay on my side at night I feel a burning sensation in my gut. When I lie on my back it subsides. Originally the burning occurs more when I lie on my left side, but now I also feel it when I lay on my right side. I eat tums, yogurt, celery, or probiotics which seems to help my stomach a little bit for a little while, but I worry a lot so I wonder if I have an ulcer. Also, I worry if my gallbladder or pancreas is involved. The pain seems to be right of my belly button about 2 inches and an inch higher.
