Hello - thanks for asking your question.
Please understand my limitations over the internet as I have neither met nor examined you. It is also impossible to diagnose without seeing the lesion myself. This information is for patient education only. Please see your personal physician for further evaluation.
Followup with your personal physician is essential.
Folliculitis is a possibility. The lesions of folliculitis are often multiple and measure 5 mm or less in diameter. They are erythematous (inflamed) and may have a central pustule at the peak of the raised lesion. Lesions usually cluster in groups and often are itchy.
There are many causes of folliculitis, including bacterial, fungal, viral (i.e herpes or molluscum), or syphillis. The treatment would depend on the cause (i.e. antibiotics vs antivirals vs antifungals). It is possible that areas of foliculitis (folliculitis) are more prone to future infections.
Another consideration may be molluscum. Molluscum causes a chronic localized infection characterized by firm, dome shaped papules with an umbilicated center. The lesions may appear anywhere on the body except the palms and soles. They are single or multiple 2 to 5 mm papules with a shiny surface and a central indentation or umbilication. Skin lesions due to cryptococcosis or histoplasmosis may clinically resemble molluscum lesions.
The infection is usually self-limited and spontaneously resolves after a few months in immunocompetent patients.
You may also want to consider genital warts. Lesions are flesh- to gray-colored and have either a smooth or jagged surface and may vary in size from less than a millimeter in diameter to several centimeters when lesions coalesce.
Without seeing the lesion, I cannot be sure what it is.
