What could cause a headache by eyes & forehead?
I was in the mountains yesterday for most of the day. I kept drinking water when I could. I started to get this headache by my right eye mostly & across the forehead before falling asleep last night. So I put some doterra deep blue on my forehead & back of neck to see if that would help since when I closed my eyes it seemed to be worse at times. This morning when waking up it was still there. Any suggestions on what to do or what might have caused would be great. I'm going back to the mountains today but as long.
