This is Dr. David
I am sorry you are having pins and needles in your hand
it sounds like you might have slept on your arm
or you could be having carpel tunnel syndrome.
do you work on the computer frequently?
this can cause increased pressure on the median nerve which goes through your wrist.
and this can cause pins and needles of your thumb and index finger.
you need to try to elevate your arm and ice your wrist.
and see your doctor about possible carpel tunnel syndrome.
let me know if you have questions
