Unclear

I was diagnosed with RA last summer and started plaquenil  a few months ago.  The really bad pain in my hands stopped and I can knit and crochet again, thankfully.  I do, however, feel different.   I can't truly explain all the feelings, but some days I'm fatigued.  I rest for about an hour and Im good to go again for a while.   I have felt this way for years and wonder if the RA was in my system then but without any signs in my blood work. Also, several years ago, I developed some blood clots in my peripheral artery in my eye.  Every test was negative.  No explanation.   Then I read an article that books clots sometimes are a precursor to RA. Has anyone had this experience?   I am not letting this stop my from doing what I like to do, just slow me down a little.
