Hi there...
A Rheumatologist would be able to check for the HLAB27 marker. My family doctor tested me for it first then shipped me to my Rheumy a few years ago.
Welcome aboard! The PENS sounds very interesting. I have used a Tens unit..but on my upper back and shoulder where I flare pretty ugly..it seems to give me more pain and spasms...even on a low setting. I usually end up with the ol' heat and ice rotation routine.
Take care !
