Dear friend, welcome to Chat Doctor! It is saddening to know this. He has a skull infection as per your description and is behaving irrelevant, becoming Chat Doctor. This indicates chance of getting meningitis or brain abscess. This calls for urgent admission to a hospital, a CT scan of the brain, urgent antibiotics NAD if required, other life-saving interventions. You have to do this despite he's refusing or behaving abnormal and rush him. He may slip into coma soon, throw a fit or worse.  Take care, and please keep me informed of your progress. Good Luck! I hope to have answered your query satisfactorily. Thank you!
