I don't know what's happening here. I've had my chair, monitor, keyboard shelf, etc. at the same heights for close to a year. This week, as soon as I sit down, I get a horrible headache, my shoulders feel like they're touching my ears and the muscles from neck to shoulder are screaming for me to get away from the desk. The monitor doesn't seem to be at the right height either.

And, no, I'm not paranoid that someone snuck in my house and messed with my desk.

I've been adjusting my chair, adjusting my keyboard trying to get some relief, and it's not happening.

I can't be in pain like this, I need to be able to work.

The only change is a new keyboard, but it can't be enough of a height difference to do this, can it? I've had the keyboard for two weeks. I just noticed the discomfort this week. (I think).
