Several times a month I have an issue where the fingers on my right hand are completely numb when I wake up. Its not like my hand fell asleep numb but numbness that sometimes takes 2-3 days to completely go away. Usually its one finger at a time that finally feels normal. I did have surgery on my right shoulder for a frayed bicep tendon last year and I started having the issue after the surgery. Also prior to the surgery my index finger would spasm and lock up when I would use my hand to cut something that was tough or thick especially if I used my index finger to push down on the utencil. Any information would be greatly appreciated.
