Who told you you have IC? iT IS EXTREMELY HARD TO DIAGNOSE & ONLY BY A CYSTOSCOPY, BIOPSY & OTHER TESTS & IS NOT SIMPLE.. If you drank a lot of cRanberry juice & felt better, you do NOT have IC as Cranberry Juice is murder for an IC patient as it is an acid which is the worst for IC! I have had IC for 6l YEARS (it is incurable)& am a counselor for about 100 IC patients, belong to the ICA..a charter member..have seen at least 65 or 70 urologists, have 3 metal drawer files full of IC info and am on the IC message board on the computer, so I doubt anyone could think I don'tKNOW IC! If CRANBERRY jUICE STOPS YOUR PAIN, YOU HAVE A BLADDER infection WHICH CRANBERRY jUICE does HELP, BEING ACID.
