interstitial cystitis
"I was diagnosed a few months ago. My doctor started me on 400mg a day and 3 times a week I went in for bladder instillation. Soon after it became obvious that I am quite allergic to it. I continued to take it (with a strong dose of Benadryl) but my reactions continued to get worse, so I quit taking it about a week ago...the symptoms are back. Don't know which is worse. What else is out there ?"
