I had the pleasure of taking about two weeks off work and grad school for Christmas/New Year's. That ended on January 3rd as I returned to both. Upon doing so, I've gotten horrible headaches. Work has been hitting me with 5-6 hours of meetings per day, and I've been in class on weekends (and homework in my spare time). I've been wildly busy, the weather has been horribly cold in NYC. 

Wondering if anyone experiences prolonged tension headaches? It's mainly tightness, sometimes pain (but, usually just tightness) on the sides of my head. My jaw is also sore and really tight. When I lay down for bed or turn the lights off and watch TV, they normally go away. Anyone else have a similar experience?

I'm wondering if this is just stress/anxiety.
