Had a slight tension headache begin to form behind my eyes today because I had to deal with a rather stressful situation with an antagonized customer that left my coworker in tears and me just trying to make nice and the stress of that tensed up my neck which began to tense up my other muscles in my head.

But thankfully an Excedrin and drinking more liquids and eating some food once I got home from work appears to have negated the headache so yay.
