Pinch the bridge of your nose while your eyes are shut, not hard--just so you can feel a little pressure.  Deep breathing can relax your tension.  If you use me while breathing deep, I can help.  Same Essential Oil blend as in the "Headache Buster" roller bottle.  Peppermint, Lavender, Frankincense, Wintergreen and Birch.  When you use "Headache Buster" roller bottle in conjunction with the inhaler, you'll give that headache the old 'one two' puch, and send it on its way.
Twist open, inhale into one nostril while other is shut. Then vice versa into other nostril.
