And just why do you believe that might be? Because diagnosing is so complex? Sometimes, but not all the time. But the word 'uncommon' seems to insinuate that there is something going on where a lot of folks don't get a diagnosis. I remember telling someone that I had seen 4 neurologists and came away empty. That person told me that possibly, I hadn't found the 'right' doctor. Now....I looked it up and a neurologist (garden variety) takes in 13 years of schooling on average to become a neurologist. So, so far, I have burned through 48 years of neurological education. It IS a little ridiculous. Seriously, I have gotten to the point that the first person to come up with a diagnosis? Get's a Nobel Prize!
