pain in arm is it lupus
I have had a pain in my left arm for weeks now, i havn,t hurt it or banged it. the opain is getting worse, it is only certain ways that i move it, dr advised some excercises. i now cannot put my arm around my back as the pain is horrible, I cannot stretch it up without real bad pain. i was thinking of visiting A&E at our hospital but feel a little silly as the pain is not there all of the time. It feels like there is a swelling in my upper arm. is this a flare up of lupus? i take medication for lupus but it is not a full diagnosis.
