Folliculitis hi, looks like you have developed folliculitis ( pyoderma)over the groin region.. Folliculitis (also known as Hot Tub Rash ) is the inflammation of one or more hair follicles. The condition may occur anywhere on the skin with the exception of the palms of the hands and soles of the feet. They may appear as red dots firstly and then increase in size to become red , hot, tender pus filled lesions... Avoid touching it too much. Avoid using any kind of cold dreams or hair oils..as it might increase the lesion. You can start using any topical antibiotic/antiseptic cream containing mupirocin over the lesion and Take some pain killers along for relieving the associated pain and discomfort If the lesion persists inspite of topical treatment, then you might need a course of oral antibiotics. Sometimes even a surgical reference is required to consider incision and drainage Hope it helps Dr Geetika Paul
