Well this turned into a Spirited Spitball Skirmish, no need either because medicines work differently on different people, and situations. Ointments can’t permeate my padded patootie, but binding the knee does squish the swelling down some. That doesn’t mean we can bind all joints/ pains that way since showing up for work looking like Elvira’s Gimp love interest will get you fired.
Here’s the theory on metals, by the way, our nerves work with electrical impulses, copper, or magnets could disrupt the electric signals, maybe it works for some people, but not me.
Also, Bee stings work for arthritis, by giving the autoimmune cells something else do, other than nibble at my cartilage, but, well, I’d rather not sit on a beehive.
But the best surprise is hyperbaric chambers can cure all kinds of injuries, wounds, burns, nerve damage etc., so keep an open mind!
