My stomach will get really tight and fills like it is filled with air. If I push on it I can get a belch but this does not give me much relief. It generally lasts for several hours. I take prilosec and tums but it doesnt help much. If I eat I get real nauseated and my nose gets stopped up. Its wierd I know. I am miserable any suggestions on what it could be or what would help. It happens about 5 out of 7 days.
