UCTD is the diagnostic label they use when you don't fit into any category very neatly. It's actually quite common. I meet the diagnostic criteria for RA, and that is my official dx, but I do not have RA (rheumy agrees). I most likely still have UCTD. The good news about UCTD is that the research shows that if you still have UCTD after five years (meaning it hasn't evolved into a more defined connective tissues disease like RA, SLE, or Scleroderma), chances are it won't. I was very fortunate in that I got into see a rheumy early and whatever the heck is wrong with me, I'm being treated for it. Most of us do not fit into a nice, neat little box. It always shocks me when I encounter a doctor that expects that we should.
