I don't know about the meds but I have bladder problems which are thought to be neuropathy induced. Get it checked out because if it's true bladder problems they need to be addressed before more damage is done. I didn't address it for many years as I was too busy seeking help for the neuropathic pain and the bladder symptoms appeared miniscule by comparison. In reality, though, they can result in kidney failure.
I hope it is the meds in your case.
