my lips.

hello. thank you for your time in answering my question! my skin infection question has to do with my lips.

about a week ago, my lips have numbed over and have become dry while losing it's softness.
it's texture all over was somewhat scaly with small dead skin flakes.
and then my lips dried even more, despite burt's bees chap stick (pomegranate), and cracked at the corners.
where it has cracked, there's yellow discharge that hardens over.
my lips itch (interior and around my mouth) and sting at the lip line where there are pinprick-like holes.
i've tried to exfoliate them in the shower but when i got out, i saw that my lips had irritated pinprick-like holes which i think now secrete the same yellow discharge at the corners of my mouth.

i dont think it's cold sores because there are no blisters filled with fluid as this site says. http://www.squidoo.com/coldsoretreatmentbypatty (stage three)

it's the second time i've had this. the first time was before school let out and was during finals. and now, i was stressed with going into college as a freshman.

from the first time around, there was a pimple on my lip line which i think formed because me always touching where it itched. the pimple ruined my lip line a little and also left a small groove/wrinkle where it was dry. there are wrinkles in the making now.

what could it possibly be? how can i keep my loved ones from getting it? how can i heal it? and how can i find relief from the pain of it?
