Ever heard of this "flu"? I was talking to a woman tonight at a coffee shop who said she had been the victim of a strange "flu" that had gone through the Portland area a few years back. The only symptom was a pain in the arm that she described as like a hot knife being stabbed into the arm and twisted, a pain so bad that people were asking doctors to cut their arms off. I wondered if this alleged epidemic ever actually happened (she wasn't someone I'd consider reliable) and if it did, why it would be ascribed to a flu. There appeared to be no other symptom except a mild fever. So, my questions are: 1.)What has to be happening to constitute a "flu"? and 2.) Has anyone heard of this alleged arm thing in Portland?
