Gas pains, otherwise known as gas, flatulence, bloating, or intestinal gas. We all get it. While gas pains are by no means a serious condition, it can be annoying, uncomfortable, sometimes painful, and definitely embarrassing. There are a number of things that can cause gas pains, but it is most often a result of being constipated or diarrhea. When gas builds up in the intestines it can become painful if you are unable to get rid of it with ease.
