Monday's the day
Yesterday Mom and Dad saw the Neurosurgeon again. He explained the procedure in detail, and told them it is scheduled for Monday. Apparently he'll have up to 10 years of pain relief from this. Hopefully he won't have to wait in agony for a year to get a 2 hour procedure done next time!
It could have been done sooner but Dad's blood pressure is too high right now to do it. He's staying in the hospital this weekend, they'll do whatever they can to lower his blood pressure.
It'll be great to have Dad back again.
