When I was little, and got headaches or was in a foul mood, my mom would tell me to tip my head sideways and “drain out the black ooze.” Easier said than done but the image has stayed with me, especially as I get lots of headaches. Several times today I thought of being able to lie sideways and let the headache flow out of my ear and away forever. Silence, rest and cool light would then replace the pain. Ah!
