Thanks for reading my post. I had a colonoscopy in 2006& it was normal. I also have Levator Spasm Syndrome. Levator Spasms are spasms of the pelvic floor muscles. These spasms make you feel like you have a golf ball in your rectum. I have seen many doctors, but all they do Is prescribe Valium for the spasms. There is a forum on the net, it is Tipna.(google Tipna to find it).This forum is for people who suffer from Levator Spasms and other pelvic floor problems.
Anything that gets the colon working can cause colon pains, and cramping. When the colon is active is when most people with IBS find issues with pain, cramping, urgency,etc. Thats why early mornings are troublesome for IBS sufferers. The colon wakes up when you do and starts to go to work.
When you do a cleanse like that, you are having your colon work doubletime, therefore it could cause it to start creating pain, cramps or spasms. If you find that this is still an issue and affecting your daily life after awhile, go back to the doc and let them know so they can treat it from there. Your GI should have a good understanding of what is going on.
