For six months or more, I have suffered a curious loss of feeling in the soles of my feet and a diminution in feeling as far up as my ankles. After enough blood was drawn to satisfy a phlebomatist and sophisticated tests were performed on my extremities, my doctor pronounced that I was suffering from idiopathic neuropathy. That sounded pretty serious, so I looked it up. It means, roughly, that there is something wrong with my nerves, my body is doing it to me, and they haven't a clue what is wrong.
Meanwhile, forty-five years ago I was diagnosed with asymptomatic sarcoidosis, which cleared up after a few years [according to chest x-rays], so the day after Christmas, I will have an MRI of my spine and brain to see whether there is anything wrong that is sarcoid related. I already know I am spineless. Perhaps the MRI will reveal that I am also brainless.
I am so grateful to be living near a world class medicial center.
