Hi Chris,
Welcome to the forum. Sorry it has to be under unpleasant circumstances. You will read some sad stories here but also many great success stories and stories of people who are real fighters who would not give up until they found the therapy that worked for them.
I was just searching on the pudendalhope website for a physical therapist near you who has special training in pudendal neuralgia.
http://www.pudendalhope.info/node/63 I don't see any listed in Roanoke but there are some in Virginia and North Carolina who might know of someone in your city. (Sometimes they attend the same conferences.) Since you don't have insurance, you might want to just get an initial evaluation from a really good physical therapist and get recommendations on ways to treat yourself. You might also find the book Headache in the Pelvis by Dr. Weiss helpful although keep in mind that the therapies he recommends don't work for everyone. There is no "one size fits all" with pudendal neuralgia. It's a matter of finding out what will work for you.
The best way I can answer your question about nerve blocks is to refer you to the article I wrote in our latest newsletter that you can access on the homepage at pudendalhope.org. Personally, I had partial temporary (several hours) relief from nerve blocks but then a flare-up of several weeks after the nerve blocks that were given at Alcock's canal. I did not have long-term relief from nerve blocks, but nerve blocks can be very important in the diagnosis and they do provide long-term relief to some people. Pudendal nerve blocks aren't typically given near the anal area -- they are more towards the middle of the buttocks and usually the doc will use some lidocaine to numb the area where the needle goes in. Some docs also use sedation.
For pain that is primarily rectal it's really important to remember that there can be quite a bit of variation between people in the anatomy of the inferior rectal nerve which is the branch of the pudendal nerve that innervates the anal sphincter. It can branch off of the main trunk in different places in different people. So a pudendal nerve block given at the ischial spine or at Alcock's canal may or may not affect the inferior rectal branch, depending on where it branches off. If you know this going into the nerve block, you will have a realistic idea of what to expect.

Lots of people have been treated successfully for PN, especially young people, so stay positive.
Take care,

PNE since 2002. Started from weightlifting. PNE surgery from Dr. Bautrant, Oct 2004. Pain now is usually a 0 and I can sit for hours on certain chairs. No longer take medication for PNE. Can work full time and do "The Firm" exercise program. 99% cured from PGAD. PNE surgery was right for me but it might not be for you. Do your research.
