I Have A Condition Called Interstitial Cystitis And Whenever I

I have a condition called Interstitial Cystitis and whenever I had a flare/pain reaction, it was due to food. I went without food for 2 whole days, but the pain has persisted. It isn't burning or an ergency to pee, but I always feel it every moment with a throbbing pain, it will lower in pain level for a few hours, but when I pee it returns full force. No narcotics/prescription drugs, herbs or anything that normally helps someone with I.C. do nothing for me or my pain. It's like I didn't take anything. I was drinking filtered water for 3 in half years and only a month ago learned it was the main irritant that had been causing me excruciating pain for the past 3 years! I drink distilled water. I do not have a doctor, nor a pain management facility, every doctor, even the E.R. has turned me away. The pain has disabled and kept me housebound for most of my life.
