Hi @tgsmith and welcome. I'm sorry you're having such pain urinating after BCG #4. It can be painful going the restroom after. My doctor prescribed some bladder numbing meds which does help. It's called Uribel, but there's also good ole Pyridium (aka AZO standard, OTC). Give your doc a quick call or inbox, I know they will gladly prescribe you a bladder numbing rx for some help/relief. BTW, I start taking mine the morning of my treatments. When I go to my appointment and they collect my urine sample, they know I've taken my Uribel ;)) GodBless
