A few years ago I developed acholasia, wich is a closing of the esophagus. I had surgery to correct the problem but I had an underlying problem that I cant seem to get diagnosed correctly, it comes in waves, I have a few weeks where I am fine then all of a sudden I am woke up in the middle of the nite with an intense pressure on my diaphragm and I need to belch but cant. So I run to the bathroom and the air tries to come up and it makes me gag forever until a few hours later this intensly loud painful belch comes out, I usualy have to do this a few times for relief and then I am ok for about half a day. The symptoms last a week or more and its gettin more severe, I have had almost every test known to science with no diagnosis and its gettin more severe. I have been taking zelnorm because when some upper gi tests were done I was told for some reason I am not digesting food properly and its givin me constipation and bloating of the stomach. But its reaching a point that I cant deal wth the pain of this attacks anymore, and I have never heard of and cannot find any information on my symptoms, can anyone help me :?:
