I had terrible pain/cramps in my hands/wrists radiating up my arm, and in my ankles up through my calves prior to diagnosis. Once I was on Prednisone these went away and they have only returned a few months ago when I was taken off Prednisone. I find it worse at night, I think cause I'm not busy doing things to distract me from it.
lildreamer - my understanding is that the bright red hands (my fingers have been red and swollen but I also go blue and am super sensitive to heat/cold, and I've read some people's fingers go white) is Raynaud's Phenomenon. I thought mechanics hands was when the skin is rough and cracked. Mine is mild, just rough on index fingers but cracked at the tips of each fingertip which can be very painful if deep. I could be wrong but that's how it was explained to me.
