I have Hunner's ulcurs with my IC, so I have found that cystoscopy with hydrodestension to be an effective treatment because the bladder is hyper stretched while in surgery then they inject a coating that fills up all of the tears. While the treatments have lasted about 4 years at a shot, going under repeatedly has its risks. I have done rescue instills, which are not effective for me because I have an allergy to lidocaine- which means that I have no numbing agent in the cocktail. This pretty much leaves me in a ball of pain rather than relief. I have tried the pills, which have limited efficacy, which is not surprising since it is the primary drug in the rescue instill. I have done PT for pelvic floor and while this has helped to control the flow when I feel an urgency attack, it did nothing to help with the frequency.
