I suffer from both a kidney disease and a "rare blood disease" (not quite as bad as hemophilia, but a bleeding thing) and can not take even so much as an aspirin or "Tylenol" to ease the pain of anything. You name it, I can't (shouldn't) take it.
It's been this way my whole life, so I've found other ways to combat ailments. Headache? Loads of water and a dim room to nap in. Tooth ache? Chew on a whole clove or a stick of celery (both have natural anesthetics). Cold? Vit C and zinc...and keep it coming (on top of my daily Vitamin and Mineral routine). I will only take something if I can not get out of bed--at all. But, since my body has gotten so used to no drugs, I have a pretty high pain threshold.
When I get a kidney infection, or when a cyst on my kidneys breaks open, it is normally a high dose of Cipro, a kidney drug, then off to bed to wish I were dying.
DF is a Nuropen guy--he gets headaches every week or so and pops them like crazy. One of my sisters (though she will never admit it) is addicted to prescription drugs and talks proudly of taking her Vicadin all the time (can we all say "Valley of the Dolls"?).
Overall, I think that people over-medicate themselves in the Western world. I suppose this thought is likely because I have learned to cope without, but I often wish I could teach people the "natural" pain killers I've found...
