I seem to get headaches a lot. I get them so often, that I'm starting to view them dispassionately, trying to figure out what caused them, where the sensation actually is, what positions/movements affect them and why/how they eventually go off. As such, I feel I can now publish my Headache Spotter's Guide and help out all fellow sufferers of the malady.
The Eye One
Centered around one of the eye sockets, epicentre usually seemingly in the very bone of the skull, in mockery of your vain attempts to massage the pain away. A constant, dull soreness, no throbbing with occasional flurries of excruciating pain when looking at bright light or laughing. Affected by light, thinking hard about difficult matters, blocked nose, poor eyesight. Cure: glasses, closing eyes, time.
The Neck One
Centered at the base of the skull and top of the neck, epicentre is apparently your very spinal column: the very think that makes you a vertebrate fighting back. Pain also spread around muscles in that area. Muscle pain, mostly, but with an insistence that is frankly rude, and prevents you from doing anything useful. Affected by sleeping position, weight of head, amount of nodding, dancing wildly to anything pre-1984. Cure: Neck brace, sleeping with only one pillow, neck massage, decapitation.
The Brain One
Floating freely around your cranium, epicentre is everywhere at once and makes you sad. The entire dome of your head becomes an upturned basket of pain, spilling agony out into the rest of your head and often, if you're lucky, your teeth too. Pain comes in many forms, but usually throbbing and inconsistent pain that will continually kid you into thinking its gone, before striking you down with a bolt of fire when you try getting out of your seat. Affected by everything, but especially aggravated by thirst, lack of sleep, lust and needing the loo. Cure: painkillers, silence and sleep.
Different for everyone, and probably less common than you'd think. People who've had one are obvious - you can sense it in the clear fear they show when discussing the subject, and their avoidance of anything that could possibly lead to another episode. Pain is intense and debilitating, making you disinclined to socialising, reading or being alive a second longer. Can be accompanied, or preceded by aura, which is an impossible term to define but basically consists of the brain going haywire and fooling the key senses into thinking nonsense, such as talking bees spreading from growing cracks in your vision, to the all-pervading smell of garlic invading your entire head. Or just blurriness and discolouration in what you look at. Affected by continuing to exist and all its trappings. Cure: unknown.
