Hi Clyde,
I'm having my 3rd BCG instillation tomorrow. With my first instillation, the nurse really trashed my urethra, and it was very painful to urinate for a few days. On my 2nd BCG, I requested lidocane, and there was huge difference - Much better. I'll bet your bleeding was from the catheter.
Regarding bladder pain or reaction from the BCG, I'm really monitoring this experience, and so far, it seems that I'm getting decreased bladder capacity and some burning at the end of urination on the 4th day after the instillation. There's really no pain on the day I get BCG, or on the day after. I'm not sure if this pain and swelling on the 4th day is coincidental for these last two treatments, or if it can be tied to the treatment. I'll post my findings as I move through this. So far, for me, it's been more tolerable than I expected.
Mike
