Hi and welcome,
I was also dx'd with UCTD before being dx'd with Lupus for about 5 years (beginning from my first symptoms). I had blood work that pointed to possible Lupus and Sjogren's but nothing concrete because my symptoms were too vague. It wasn't until I had organ involvement that I got my SLE diagnosis. With my UCTD dx, I was being treated with plaquenil also which I believe is very important and I think is wonderful that your doctor is doing. Some doctors will not do this even with a UCTD diagnosis so I'm glad that your doctor is being proactive. I was also being treated with prescription NSAID (Lodine) which I'm still on today.
Have you just started the plaquenil? The reason I ask is because its important to remember that it can take some time for it to take a full effect in your system and to control your symptoms. Sometimes for a few months so you may not think its working but you may have to give it time to work. If you have been on it a while and its still not cutting it, I would suggest talking to your doc because they may be able to add a NSAID or maybe even low dose Pred to help you out.
