I have been suffering from RSI in both arms for a decade now. It started after coding 10+ hour days working at a game company. The pain ebbs and flows with usage, but the inflammation and tightness has never disappeared completely.
Over the years, I've met a number of people who also also suffer from RSI in various forms. Fortunately, the majority of people I talk to suffer for some period of time, but do eventually recover, and are able to continue on with their lives having to be carful to avoid future flareups. A handful though, including myself, seem to fall into the "for life" category.
I've tried everything you can think of to varying results:
* 15+ doctors in various specialties
* Physical therapy
* Massage therapists
* Chiropractors
* Acupuncture
* Most every ergonomic keyboard and pointing device on the market
* Various desk/chair/keyboard tray ergonomic adjustments
* Addressing TMS (See books by Dr. Sarno)
* Taking a year off of work (multiple times)
* NSAIDs
This is resulting in me spending a lot of time looking into other career potabilities, but I keep ending up back writing code to some extent.
Voice coding is literally the first thing that comes to everyone's mind when you tell them you have arm pain, but it's a dead end in my mind. I tried to follow in the footsteps of Tavis Rudd, but I just ended up with voice strain from talking too much. You might have better luck though:

At one point in my life, I had an intern who knew how to code type for me. No voice rec system will ever be as good as a human who knows how to code... and even dictating this way was slow and frustrating, though at least my voice wasn't strained.
Someone else here mentioned TMS. A good friend of mine who was suffering for months with arm pain was greatly helped by looking into and addressing it. I recommend Dr Sarno's book "The Mindbody Prescription". Even though it wasn't a cure for me personally, I did find it helpful to mitigate some of the pain.
As far as creating a community goes, I've never found reading about others suffering to be any help or comfort. If anything I've found it better to not dwell on it and just move on with life.
OTOH, a resource that offered suggestions and opportunities on how to make the most of the capabilities that are still available might be nice. Knowing there's still a lot that one can accomplished, even if you can't code for 8+ hours a day, 5 days a week.
