Hi My Bf Recently Had A Surgery For His Collerbone

Hi my bf recently had a surgery for his collerbone which he broke in 3 places falling off his bike the wound was stitched and 16 staples were put in now his staples were taken out and its healing as u can see the scab ontop but hes just noticed there are a few spots around the wound and its making him itch what is it and what would be a solution or something we can do about it his current doctors is no longer his doctor due to him living too far away so i just wondered if u have any advice at all thank you
