For a few months now I've had recurrent cramps in my left hand/wrist/thumb. Probably on average once a week id say but sometimes in clusters. It's hard to explain but suddenly the muscle will cramp/contract and my hand will get sort of 'stuck' like my wrist curling in or my thumb pressing into my hand, and I can only move it by 'helping' with my other hand. It lasts less than a minute I'd say or until I can uncurl it using my other hand.
it's always just on the left side.
Should I be concerned/see the dr?
Any idea what the cause could be?
