anyone else w/ thyroid disorder causing stomach problems?

okay so I was diagnosed with hypothyroidism in the third or fourth grade, and have always had stomach issues.  everything hurts my stomach.  I've been going to the hospital and having tests ran for other diseases and etc. yesterday i had an endoscopy and a colonoscopy (panic attack x10).  i was just wondering if anyone else has hypothyroidism and experiences awful stomach issues that make you curl up in a ball and scream.
