I am a 60 year old male, good health, but for the last year or so i ve been bothered with what i would call pimples on the side of my legs, close to my waist line and on my stomach, they most generally result in an absess, and the result is a small but hard lump of puss. I ve tried anti bacterial soap, changed laundry detergent, ect. what can i use to nip this.
