Just to let you know I have had every test possible and have seen half dozen doctors and none of the specialist know whats causing my problems. They have simply labeled it as IBS.
By the way I am sure those of us in pain rather not take pills, which only mask the problem. However, if the pain and diagnoses is unsolved then we have no choice but to seek drugs until otherwise noted.
I take Levsin and it has worked wonders for me. However, it is not a pain reliever. It decreases spasm in the colon.
My doctor told me to take it for a while and see if it helped, if not he would give me something for pain. I took it whenever I had pain and found it would help a little but not a lot. When I talked to my doc about it - he said that I need to take it EVERY day, whether I am in pain or not. Once I started doing this, about a week later things got dramatically different. Now my pain is rare, and I take dicyclomine when that happens and it helps a lot.
