My story is that I broke my foot about 10 years ago (in the Grand Canyon no less). Long story short, when I eventually got the doctor, she told me that this kind of fracture always took a long time to heal and the literature suggested that electromagnetic stimulation had some benefit. Of course, the insurance company wouldn't pay until it was deemed a "problem fracture" in a few months (as my doctor thought it would be) but I did eventually get my $1000 stimulator at about 50% off.
It had the most horrible interface one could imagine. If it slipped off the foot, it apparently simply shut down for that day's stimulation. In any case, my foot eventually healed.
A few years later, a friend had a similar injury. I gave her my stimulator. Apparently the allowable stimulations had expired by then. She took it into a medical supply place and they were horrified by the idea that they might simply reset the device.
I'm not a big pharma hater but this sort of story is why people get really mad.
