on the roof of my mouth near my central incisors (the two front teeth, of my top jaw) there are these vain type things (i really don't know what it is called. as you can tell.)

it was painful but now it isn't, I'm just curious as to what it is, or if it will go away? i haven't noticed it before, but then again it is hard to see :S

if you look at the roof of your mouth near your incisors there is a bunch of vein looking things laid out like a set of branches, but these are pink normally. and at the moment there are a few ''branches'' of mine that are white

thanks for any help
