@granite, I also added your question to the Cancer: Managing Symptoms support group. I believe that @greglynch7 may have had a plexus nerve block for pain in the pelvic region related to prostate cancer.

In the meantime, you can learn more in this helpful article

Have you had the nerve block or will this be happening soon?
