I haven't been felling since midnight jogging?

Ok so me and my friends went midnight jogging when it turned 2011, oh yeah it was like 20 degrees out and we ran a block. Ever since then my thumbs get a bit twitchy every now and then and so do my knees. And today my body started felling very weak, my head is pounding, my ears are sensitive and that's not helping the head ache, and i feel light headed, but i don't think those are from the jogging. Can anyone help me out.
