Sometimes all the fingers in my left hand freeze briefly.
It always happens when the fingers are in a position similar to sign language letter P but all fingers touching the thumb. I don't sign, its just for reference.
I'm 30, male, left handed. There is no pain, so I'm looking for an answer other than Trigger Finger. It just started this past half year but has happened about 5 times already.
It usually happened at work when using a screwdriver in a difficult to reach place, its a bit worrisome because I am a large industrial machine technician and it could lead to injury.
Any ideas what it may be?
