Let me just start by saying that I am a hypochondriac. I am a 24 year old female. I have been having bouts of constipation and diarrhea. I have been having stomach pains along with rectal pain whenever I sit down. Now me being the hypo that I am there is only one word on my mind, cancer. I went to my PCP today and she is treating me for constipation right now. She wants to see me back in 2 weeks and if I'm still having symptoms she wants to send me for a colonoscopy. Anybody have these same symptoms?
