Ended up with a slight headache at work today.
It started behind my left eye because I was stressing over a situation with a guinea pig, but that ended up fading once I took a nap on my break and had a heat pack over my eye. 

But then the headache went over to the right side behind that eye as the morning progressed. I think because I could hear a faint...humming singing sound from somewhere nearby. 
And it was just faint enough like the faint buzzing of a fly or something that if you weren't paying attention you probably wouldn't realize it was there. But I could sense it...this faint humming.

I ended up going to investigate.
Couldn't really find it...I did encounter a customer at the birds talking to the conure and she hadn't moved from him in sometime....so she could have been the source as after she left...I didn't actively hear the humming anymore.

In any case.
I ended up getting some of my PastTense Essential Oil and placing it on my tense muscles, took an Excedrin, and grabbed some crackers to snack on to hopefully help it fade.

Which it did. Yay.

Hopefully it stays away.
