When i wake up i always have abdominal pains. what does this mean?

Trapped gas: If you don't move much in your sleep, you may have some gas that is not travelling through your GI tract and resulting in abd discomfort. That being said, there may be more to it if it is not intermittent and not relieved by passage of gas. Depending on severity, duration, associated symptoms, and other factors, this could warrant an exam. Hope this helps!
