Cindy, I moved your post here to "non-invasive." And we hope that the BCG keeps your here!
Yes, your experience is very normal. The purpose of the BCG is to stimulate the immune system in your bladder lining where you cancer is currently located, to fight that tumor. The more BCG you are exposed to, the more reactive and sensitive the bladder lining becomes to it and you are experiencing that reaction.
This tells you that the BCG is having an effect, which is exactly what you want to happen. You will probably continue to have more side effects as the treatments progress.
And, if they become too severe, the urologist can reduce the dosage. It will still be effective.
This is uncomfortable, but much less so than systemic chemotherapy, and the reward of most likely stopping this in its tracks is well worth it!!
Been there. Done that!!
