I touch my face more because in class the only thing you can rest your head against and still appear interested is you hand, so head on hand = 3 years of pain and sickness.
I think it can also be because our bodies are working so hard at helping us heal that it does not have time to fight little bugs.
Fell off a horse in late winter of 2009 blacked out for a couple seconds, had amnesia for 10 hours (still don't remember this time), had 2 CT scans, 2 MRI's, 1 MRA all negative. Since the first concussion I have continually knocked my head into different things purely by accident or from being stupid. These many concussions over a short period of time have caused
constant migraines, nausea, and dizziness/lack of balance.
Migraine triggers are:
light sensitivity (especially to florescent or bright lights)
sound sensitivity (especially to high pitched or loud sounds)
temperature sensitivity (especially to cold or extreme heat)
activity (especially if breathing increases or head is jostled)
pressure on head (sinuses, hats, headbands, sunglasses, pony-tails)
lacks or quality (food, sleep, water)
tension (stress, tight muscles, tired eyes, sickness)
