You should post those pictures on the "Ask the Docs" forum. They could be anything from insect bites to ingrown hairs. Take some even closer more detailed photos from various angles as it's hard to tell without actually seeing them up close and palpating them. Regardless you have to watch closely for infection, feel for increased heat & pain radiating or streaking from the site. Cellulitis infections are no joke. Good Luck & G-D Bless on a speedy recovery
