Hi Kitty,
I had IC symptoms too. At first I thought I had a bad bladder infection - I got antibiotics and they didn't do anything.
After a night in pain and urinating almost 20 times one night, I went to the Hospital. As usual, they found NOTHING.
So I chalked it up to lyme. I went and ordered a tincture (i'll check the name of it when I get home in case your interested) of herbs for bladder health. Even trusty old Buhner has herbs for IC. However by the time my tincture arrived the bladder symptoms disappeared and haven't returned.
I really think it had to do with lyme and co.
