Step 1:
Don't put any more needles in your thumb. Stabbing the pads of the fingers causes pain because they have one of the highest concentrations of nerve endings anywhere in the body.
Step 2:
Get a hobby other than stabbing your thumb with needles, thats just dumb, and produces an obnoxious pain.
Step 3:
Wait for your thumb to heal. It will stop hurting on its own in a couple of days, assuming the puncture doesn't get infected.
