Is there a connection between CPAP and painful gas?

There can be. It's called aerophagia. Some people have a lot of problems with it and some don't. It can be pressure related---for some people, aerophagia is not a huge problem when their pressure is below some fixed number, but once the pressure is above that number, the aerophagia starts. Others have problems regardless of how low the pressure is.
Or the problem could be something unrelated to PAP, such as GERD. GERD occurs when the lower esophagus sphincter does not stay closed properly and when it is open, it allows acid from the stomach to move into the esphagus.
If you have GERD problems, the chances of having aerophagia problems goes way up.
readyforsleep, There is another thread here titled Aerophagia which has some good info on the condition. I too am very interested in this topic.
