(And for anyone else in the same boat), I've been down a similar road as yourself. If at all possible, try to steer clear of surgery. The MD's wanted me in surgery, but I said no and went with what is linked below. I did just that and am in much better shape than years ago.
Look at this closely and prior to meeting with the surgeons... NUCCA.ORG There is one in PG.
I have a few friends who have gone the surgery route and haven't been the same since.
Thanks again for all of your photo work on the SC Branch. I haven't down there in years, but remember it from its SP days.
