Had a slight headache today at work....because my eyes were bugging me in that one contact was acting like it had something in it though I couldn't find any tears or such to cause irritation. And yah...it formed behind my left eye even though the left eye was the one being irritated. *exhales* Thankfully some Excedrin and a nap with a heatpack while I was on break helped to make it go away. :)
