That is likely to be due to a bacterial infection. A check up, proper cleaning (with hibiscrub or betadine solutions) and a local (ointment) antibiotic would be needed. It would be best to have a buster collar to avoid him licking the part. Often those ointments have anti-inflammatory meds inside as well.
