Is it RA or Peripheral Spondylitis?

Anyone ever heard of Peripheral Spondylitis? I have been doing a ton of reading after my doc mentioned it and am trying to find others who have heard of the diagnosis. So far I have had two rheumy's with two different opinions. One said RA and the second is still "undifferentiated', but last week, he had an "aha" moment when we started talking about horrible plantar fasciitis in my feet. I have also been diagnosed with tendinitis in my right wrist and flares in large joints. We are still trying to figure out my flares that have become WAY more frequent in the last three months. My hands don't really have painful flares or swelling, more mechanical mix ups where they don't work so well. I don't have the back pain associated with more traditional ankylosing (axial) spondylitis. Anyway, everything I have read seems to point more to Peripheral Spondylitis. More ultrasounds in a few weeks, but in the meantime, if anyone knows of any forums or support groups for Spondylitis, please let me know.

Thanks!
