My daughter has knots in her fingers, elbows, feet, temples and other places, too. Her hands feel like they are on fire and she can barely open and shut them. No grip at all. She had blood tests for RA, lupus and lyme disease which were all negative. Blood tests did show inflamation. We are at a loss for what can be going on with her. She has had this happen before but, it always went away. This time it isn t going away even after steriod pills. They didn t seem to help much at all.
