Yes, Lon - it's the arthritis. The doc says the primary cause would have been the months and months I had with such ridiculously high levels of inflammation - my CRP was over 100 at the worst and it was like that for a long time. He described the calcification process to me.
It does help to explain why the methotrexate has helped my hips, feet, hands and wrists fairly well but not my shoulders.
