What could this be and why has he taken it? A worried mum, thanks [/INST] Welcome to HCMi appreciate your concern about your son's healthThe symptom you are telling points that are your son is having a boil which has eroded and pus has come out.Dont worry pus oozing out is a good sign.just take care of cleanliness so that it does not turn into an abcess.keep cleaning it with methyl spirit.let it dry.dont apply creams.if it persist for two or three days give him a 5 days course of antibiotic like amoxicillin and see a physician. </s>
