This is not really a disease. It is more of a condition. From my research it appears that there is a damage that causes the body to not produce the mucus of the bladder. The nerves are exposed and acids tend to make the nerves go crazy. It also gets agravated by bowel movements so you want to have a soft stool. It looks like when one goes to do # 2 the nerves are all conected going through the spine and the bowels make them irritated. That is why when you are constipated or after you go to the washroon you fill a little worst for a few minutes.
Once again, diet (it sucks), Flowmax works for me and Cista-Q. May not work for you. Elmiron did nothing for me. Baking soda.
Sorry, I wish ... it sucks I got nothing else to say.
