Ended up with a headache at work today which considering I've had one like for the past week isn't surprising at all.

It persisted throughout most of my shift, but I was attempting to drink and eat food a little more often as well as working out the muscles in my back when I could....
Which something in there seems to have helped. 
Because the headache has faded away for a bit and the muscles in my back are less tense.
So yay overall.
