Hello, Welcome to healthcare magic. You may be having recurrent furuncles, which is an infection of the hair follicle. It is common in the pubic region especially if you have itching due to allergy/ yeast infection. Scratching the area introduces the infection into the hair follicles, which get inflamed and become red, swollen and painful. You will need a course of oral antibiotics like Cloxacillin or cephalexin for 5-7 days. You could also apply antibiotic creams containing 2% mupirocin or 1% fucidic acid. Hot compresses also provide relief. Hope this helps you. Take care.
