Clitoral 'pimple'(?)with hyper sensitive(painful)inner thigh

So hard to describe.

i had intercourse with my boyfriend, and then the next day i developed this.. (for lack of a better word)pimple on the lower left side of my clitoris. The first day it would throb (not agonisingly painful- but much discomfort like a twinge) it 'hurt' enough it would interfere with my sleep.

Second day now, the painful twinge in that area is sort of gone, however there is a hyper sensitivity (painful to touch even lightly) my inner thighs, backs of my legs, even my lower stomach area below the belly button. i could swear even my feet feel 'wrong' too when i walk.

Once and awhile i get the same painful twinge as mentioned earlier- only in my lower belly region moreso then my vaginal area now.

The 'pimple' on my clitoris is very red, VERY sensitive to touch (i'm trying to keep the area clean and whatnot), and there seems to be a tiny white dot on it as well.

i don't know what this is... i'm really hoping it will go away- just the odd twinging pain that has spread has be a bit worried.

my boyfriend and i have been together for almost 2 years, i have not been with anyone else, and he swears the same.
