Andrew......ouch........its not uncommon for BCG to become more painful with each series which is why it is recommended that it be reduced to l/3 the usual dosage and you certainly need someone who is qualified to do the instillation which appears not to be the case. Improper instillation can cause strictures of the urethra and i hate to think what she might have done to the bladder.
You said its been a year and a half since your diagnosis ..you said stage 3 but i think you meant Grade 3....Stage 3 would be invasive.
Have you had any recurrence? Does your uro do routine poke and peeks?
Have you considered a second opinion?
I don't know where you are but its very common to not only get a second opinion from a top cancer facility and also to get a second TURB. All uro's and pathologists not created equal.
You should not be in that much pain. Let us know where you are and we can refer you to a top facility.

P.S. Here is Dr. Lamm's protocal for BCG
