I've had a headache off and on behind my right eye for most of the day. Which is frustrating. Especially when Excedrin and heat packs weren't really helping to get rid of it. *exhales* I'm thinking it was tense muscles that triggered it. But it could also be the shifting of my sleep schedule since work is edging me back into working earlier in the morning rather than later so perhaps my body is complaining about the shorter sleeping schedule....
