I woke up twice this past week withy fingers tingling numb on right hand. Took a few minutes to go away. I've read it's possibly carpal tunnel?

Numbness. This depends on which fingers were numb. If it was the thumb/index/middle fingers then it is likely carpal tunnel(pinching of a nerve in your wrist. If it was the ring and small fingers then it could be cubital tunnel syndrome(pinching of a nerve in your elbow). It is also possible that you could have a pinched nerve in your neck (cervical spine) that caused radiating numbness to your fingers.
