I know the feeling...just went to another doc/hospital for a scan of my throat on Monday. That was set up by another doctor that I've stumped. The scan was normal, but doc after doc after doc. Either the human body is much more complicated than anyone except God knows (that is believable) or the STATE OF THE ART ( ya gotta say that with as deep a voice as you can muster) medical knowledge and treatments just aren't so hot. Keep on keeping on, Sonny. It is much easier to maintain inertia than to start something moving.
