Okay, I'm worried.

Today (actually, right now) I am experiencing a very strange feeling that started not too long ago. I've felt it before, but it was rare, but it did happen - today, it started about an hour and a half ago. Its this weird feeling that I feel on the skin of my face that feels all fuzzy as if some weird, prickly, stubby thing were constantly rubbing itself against my face, and my chest feels the same, and inside my chest, i feel like something is pushing the insides of it in, like sideways gravity. Is this just something weird and specific that is only happening to me, or what? o.o" I don't really know how else to describe it.
