I've been having many stomach pains, and constantly having to go to the bathroom. The felling of having to go to the bathroom is always there, and it stops me from eating, this has been going on for about a year now, and it's getting really annoying while I'm at school or somewhere, and I spend a bunch of time in the bathroom but the pain and felling of going to the restroom is always there. Is there anyway to stop this from happening?
