I had this since 1995 but in sept.of last year it really got bad I went to the doctor twice a week and nothing helped so I got on the web and read artical about (IC) and have started treating myself. I take a Doxycycline 100mg once a day or twice at first if you are hurting bad. I also take (Prodium) over the counter medicine for a urinary infection and it makes your urine red about 3 or 4 times a day one at a time it will say 2 but I take one. I also use baking soda to take a bath in and to douch with about once a week. All I drink is water now. But this is doing the trick for me. You can ever drink baking soda and water once a day. I hope this helps.
