Dr. Ellis on the old Yahoo board frequently cited fibrosis as a cause of our inflammatory-based pain. My layman's understanding was that he was saying the same thing as Dr. P. when he talks about Wallerian Degeneration of the nerves. It sounds like you're saying the fibrosis is in the vas itself (along with the nerves it has), not just the nerves.
I tend to believe I have what you have. Thanks for posting and keeping us up to date.
