question: I am 51, weight 125 lbs, and have the first sypmtoms of Rheumatoid Arthritis, mostly in the heels of my feet. The last couple of days, my knees are not to the touch. I can feel the heat radiating from them but I have no pain, redness or swelling. My hot knees occur several times of the day and last for an hour or so, sometimes longer. Is this more RA symptoms? What is my body (knees) telling me?
