Sorry to hear that. I dealt with BPH for a couple of years. Fortunately, my PSA has been normal. Had two treatments to reduce the size of my prostate and that’s been helping.
You mentioned nerve issues. Related but separately, there’s also a thread on Pudendal Neuralgia . I don’t know if this applies for you but sharing so you have it. I’ve been dealing with PN and that thread has helped me.
