Every morning I wake up with my left ring finger locked in a certain spot, and after that, every time I try to move it, it locks in the same spot, and it moves with some force, it gradually improves as the day progresses but it's the worst in the morning, and I also feel it sometimes when my hand has been in the same position for too long. It is usually limited to the ring finger, but rarely it does radiate to middle/little finger. Has been going on for at least 3 months. Any advice would be appreciated.
