We ALL get those from time to time. My experience has taught me this though.... When your skin is dry (not even that dry) and you shave you open and irritate those pores. Lots of times you use a thick body soap in the shower or put lotion on after you get out, and because you opened those dry pores from shaving you clog them. My advice... use lotion on your legs HOURS before you shower, and use a body soap with little scrubbies in it (I use St.Ives Apricot scrub). Works great for me, should for you too. Good luck, let me know if it works.
