First off, stay away from google/searching it. Thats the worst thing you can do.
I get that all the time. It's just gas pains and it can double you over in pain, I know. You probably had to use the bathroom, or you may even be somewhat constipated. Like I said, I get it alllll the time and that's all it ever is. Try to walk around and drink warm water (with lemon if possible), it'll help get things moving
