Sara Anne,
I'm so sorry to hear of your terrible discomfort. I don't have CIS so I can't say whether it's normal to have these symptoms for so long. There are others here who may be able to help you with that issue.
However, having endured 12 BCG treatments, I CAN tell you to expect burning and bleeding on account of BCG alone, so, on top of the continuing burning and bleeding after TURB's, I would say that it's not gonna be too much fun. I think you should probably give it a TRY, though, IF that is what your Doctor is asking you to do.
We have a friend here at the forum, Warren, who was Dx'd about 7 years ago with CIS and was treated with Mitomycin. He has not had any recurrances. (Hope I'm telling this right, Warren)...
I guess my point is, that if BCG is intolerable to you, there MAY be another option.
However, my understanding is that BCG is the treatment of choice for CIS.
Take care. There are lots here who will be able to help you through this ordeal.
Your friend,
Rosemary
