 I've been having cramps/stomach pains almost nonstop for two weeks of varying severity.

You know that pain you get below your belly button after you ate too much candy and need to poop?  
You know the cramps you get when you are really nervous about something and keep wanting to poop?

Yeah, it's kind of like that, except usually it's supposed to go away quickly. Not be here for two weeks!

The cramps are usually mild, sometimes so faint to the point where it's almost gone. But sometimes it flares up again. It seems to change locations.

\-Sometimes it's the pain right below the belly button like when you had too much candy.  
\-Sometimes is cramps along the left side with a light stabbing pain in the middle of the abs.  
\-Infrequently, the cramps move to the right side.  
\-Sometimes is a general achy, burning sensation that's not in any specific area.

So far I have been able to ignore it mostly. I actually walked around for miles recently, so it's more disturbing than it is disruptive. But I keep feeling like I need to poop and my butt keeps trying to push poop out when there's nothing there.

It's basically just a near constant cramp by itself that is disturbing. Sometimes it almost fades out, especially when I just wake up an don't sit up yet. But then it comes back.

Does anyone get near constant cramping due to anxiety?
