Sharon, I developed my symptoms about 4 months after completing salvage RT, my level of damage is quite rare .
I finished up going out of area for a second opinion, the prof took me into theatre and when I came round he said, there is severe radiation damage and unfortunately it is beyond help.
There are bladder infusions to treat the problem. I tried hyperbaric oxygen treatment but as I say it was all too late. Ask your medical team what experience they have dealing with radiation cystitis, my problem was urology blaming radiology and radiology blaming urology.
To to repeat my level of damage is quite rare, but don't get fobbed off.h
Thanks Chris
