@denis76 - Thank you for the prayers. I consider myself very fortunate. I haven't lost function, so nerve damage is minimal. I've seen and read of much worse. North being in that group. It just hurts which is causing reduced mobility (and interrupted sleep). Taking a full step is out of the question. I'm hopeful that resolves once zapped next week. If not, PT here I come.
You are correct in that the lowest my PSA dropped to was 0.19. Never made it to undetectable.
What kind of mushrooms?
