Thanks, all of you. Even though it hurt really bad yesterday (and I was worried that it would never stop, or get worse), I did make it to work and it didn't bother me too much there (except when the clients opened all the windows in the van, and blew air at me with paper fans - it was hot and they were trying to be nice and cool everyone off).

Today it's okay. I don't know for sure what was wrong with it, but it's down to just being slightly irritable. I think I'll avoid contact lenses today, but it will probably be good enough to wear them by tomorrow.
