Silverlady---There was a time when I had symptoms that seemed like IC. I went on the IC boards and read about it, and felt terrified. But then I found a book by Larrian Gillespie--You don't have to live with Cystitis, and she connected bladder pain to low back pain and nerve pain from the lower spine.

I found that attending to my back significantly decreased the bladder symptoms. It might be worth looking into.
