For about two months I have been unable to fully straighten or fully bend me left elbow. It feels like there is cotton stuffed inside my joint. It feels tired most of the time until I try to move it past the range of motion I have left. Then it hurts. I did discover that when I put direct heat on it last nite it loosened up but this morning it is frozen worse than ever. Anybody in the RA Club have any insights on this? It's the only joint that does this. The rest are swollen and painful but they don't have this frozen feeling. I tried to google it but I must not have been putting in the right words. Thanks!
