I have another headache forming behind my right eye again.

I'm guessing it's for the same reason as last night. Eye strain from my contacts. Though with how tense my shoulder also feels it could also be tension related. Or even lack of food/water related as I haven't been eating as well today as I did yesterday though I've gone and grabbed some soup and something to drink. So hopefully that helps my headache to fade. 
I'll probably end up taking my contacts out soon as well. Though we'll see how the Excedrin I also took affects the headache first.
