baffling abdomen / bowel pain
I'm not sure my discussion title is right, but it was all I could come up with. Here is the problem. For the past several months, I have experienced bowel movements only every two days. The problem is the consequences. About 30 – 45 minutes after the event, I start experiencing pain in the rectal area, aching and burning, and it gets worse with time. Ultimately, the ache moves to my lower abdomen as well. Often I simply have to go to lie down to deal with the discomfort. The pain continues for around 4 hours and then it just goes away — at least it has so far (knock on wood!) — and I'm able to function quite norrmally. I have been prescribed neurontin (one in morning and one in evening) and norco as needed (I try to avoid taking this), but nothing seems to be a great success in dealing with the pain. I do take a stool softener each evening but I'm not sure what impact it has. I did go to a GI doctor who did a colonoscopy and found nothing and put me on a gluten-free, lactose-free diet. I have fudged the gluten and lactose from time to time as an experiment and I have seen absolutely no impact on my symptoms. So my questions are: any idea what my problem is and what sort of a doctor should I visit next? Anyone's thoughts greatly appreciated.
