Help, I have loud painful burping and cannot find out what it is
Since March of 2004, I have had painful burping with stomach pain. I was told that I had IBS in 2000, but did not burp the way I have since March 2004. When I go to bed, I have to sit up and burp several times. Then if I wake up to go to bathroom, I'll have to burp. I cannot burp lying down, and the pain will not go away unless I sit up and burp. I have been told that I swallow air and to try these exercises. Did not help. Anyway, I think I may have no digestive enzymes or something like that. I just don't think that is all of it. Is there ANYONE who knows or has heard of this?
