Around 6 months ago, my left
middle finger’s
middle and bottom joints around the knuckle areas, started to be painful, particularly in the morning. When I tried to bend my middle finger, I feel the joint movement not smooth, kind of snap and bounce like a toggle switch.
I am unable to fold and curl my middle finger back to touch my palm, like trying to hold a fist. When I put my finger in hot water, the joint movement is smoother and less painful.
