best thing for fingertip pain is nerve glides.

feet shoulder apart, knees slightly bent.

the waiter - arms at sides, palms face forward. bend both the elbows and the wrist and bring hands up until you are in a position to be holding a waiters tray.

tennis elboe - arms straight ahead, make fists with palms down, rotate so palms are up, rotate so palms are down, bring arms down.

scalene - one arm hangs down. bring other arm up to the side, that hand is a fist pointing down, rotate it to point up, bend the wrist up, and tilt the neck away from the up arm. rotate wrist down, lower arm. switch arms.

do all these really slow. dental floss for the nerves.
