For the past year or so I have had frequent but sporadic episodes of extreme lower abdominal pain. It feels like someone is grabbing and squeezing my bowels and the only way to release the pain is to pass gas, and then the pressure typically just builds up again. My doctor has sent me for x-rays of my upper chest area and has sent me for an upper GI as well. They have found mild to severe acid reflux but I can't help feeling that they aren't seeing the problem because it's lower than that and I don't seem to get a lot of chest pain. If anyone can shed any light on this I would be really appreciative!
