My son(1.2mc) pus in right gluteal region for 6 months.report showed few gram positive cocci.it was discharged by operation.but again it is grownn.why?

Recurrent problem: You are not specific about the region. Recurrent infections near the opening of the anus can be due to a fistula from inside the colon bringing germs to the skin apart from the anus.Recurrent boils on the skin of the buttocks often reflect a kid who carries staph in his nasal passages and loads up his/her fingers.They scratch the area and a boil can form.
