Infection after getting two wisdom teeth pulled, couldn't eat for a week, could only drink after gargling Difflam. Also did something to my back, think I trapped a nerve, could only get out of bed by sliding out onto my knees then doing a "1-2-3-go" to stand up. Migraines.
Orgasmic cephalalagia - had that for while, but hasn't happened for several years. It's a type of migraine that starts just before orgasm and can last for a day or two. Very painful.
When i was in Nam i had my left leg blown off and i just picked it up and hopped back 5 miles to the chopper and was flown to the medics 100 miles east. Nipped a bit but just got on with it.
