I Have Been Diagnosed With RA Several Years Ago, Now

I have been diagnosed with RA several years ago, now I am feel much worse, temp of 101 most of the time, hair loss, more joint pain than usual in wrists, ankles and knees. I do have a tare in my shoulder that I am working with a surgeon with now with meds and excerise. I am concerned about Lupus, my age is 67, normally I am very very active but now am so tired I can hardly do anything. Any suggestions?
