may be tmi for some of you, but please answer.

okay so I shaved my vagina Saturday.. last night (Monday night) it started itching like crazy! so I had what looked like scabs? from scratching. 6! okay so I was taking my underwear off and one fell off and it looks like there's a hair underneath the "scab"?! what the hell?? I've never had this before. is this razor burn? ingrown hair? or what? what can I do to ease the itchiness and get rid of these scabs? please answer!
