I was finally diagnosed with IC in Jan 00 after a cysto w/Bladder Hydrodistension. I had seen several Ob/gyn specialists until one decided my chronic pain was coming from my bladder. I am now on a drug study using Elmiron and Atarax or the placebos? My frequency has decreased, but the excrutiating burning continues. Does anyone have any positive news about the above drugs? And are there any serious side effects of Elmiron?
