Is It Normal To Find Eyes And Throat Spasming?

at about 3pm today, i was at work and my right arm started spasming very hard about every few minutes. Then my right eye started spasm also. Now my arm and eye are spasming as well as possibly my throat because it sounds like i'm pushing out puffs of air through my nose. i haven't done anything out of the ordinary today, and it's starting to worry me. any suggestions?
