DOCTOR DID A BIOPSY ON A KERATOSIS SPOT ON MY

DOCTOR DID A BIOPSY ON A KERATOSIS SPOT ON MY SHOULDER THAT HAD A RED RING AROUND IT. HE REMOVED THE DARK SKIN BUT THE RING REMAINS. (LAB RESULTS CAME BACK BENIGN) THE RED RING IS WHAT HURTS, THOUGH. IT IS VERY ITCHY AND THERE IS SHOOTING PAIN PERMEATING FROM IT AT TIMES TO MY UNDERARM, RIB CAGE, OR A DEEP STABBING FEELING ON MY SHOULDER BLADE. I AM NOT SURE WHAT TO DO ABOUT IT.
