Why do my feet hurt when I'm about to have a bowel movement?

[PinkPlaydoh]

For the past month now, I have had chronic diarreah. Everything I eat, gives me diarreah. It is extremely painfull. I get cramps that radiate into my legs and down to my feet. I am litterally screaming in pain, in the bathroom. I have had this problem since I was a kid, and it seems to have gotten worse recently. I can't eat anything without getting bad cramps and diarreah. I have to drink half a bottle of pepto bismol, to keep myself from spending hours in the bathroom. When the Pepto wears off, I will get woken up at 7:30 am, with bad gas and cramping. Then the diarreah will start up again. It will hurt really bad, and then I'll have a movement. Then  I feel ok, and then a minute later, the pain and another small movement comes. I now have a dull aching that shows up in my feet, right before the cramps and bowel movements start. The pain gets worse right before I have the movement. I can't take it anymore! This diarreah is controlling my life and making it very hard to do normal every day things. I'm stuck at home sometimes cuz I can't stop going to the bathroom. The pain is excruciating and nothing seems to make it go away. I take immodiums, but they're expensive and when they wear off, I feel like I wanna die. I have been to doctors for this same problem, minus the foot pain, and they give me the same line of bull. "It's stress." It's not stress! I have nothing to be stressed out about! My life is pretty peacefull. I'm desparate for answers and some kind of relief. I'm hoping someone can help me out here. I've tried telling my friends and they tell me I'm insane an that it's all in my head. I just wanna scream when they say that to me. I feel like I'm all alone in this battle and there is no hope of winning it. Please, anyone, if anyone out there knows what's wrong, please tell me!!

I have the same problem, though not as extreme. It has been getting worse the older I get. My mom has had the same problems since I can remember, so has my grandpa. If you find out the answer, I would like to know. I have had several tests and they all come back normal. I have AS, but I don't think that is a common denominator.
