Let me be clear. I have had this problem for 13 years in my groin and armpits. I have tried everything under the sun, multiple anti biotics, different soaps, different vitamins, many topical oils and gels, and many other things.
Hydrogen peroxide is the only thing that works for me. It doesn't make it go away, but it reduces the pain to almost nothing. It also keeps the boils from recurring as frequently as they did before. Simply get a spray bottle, heat it in the microwave to where it's hot (Not intolerable) and then spray it on the afflicted areas once or twice a day.
I hope this helps!
