You have already received much better advice than any I could offer. Like PeterDA said, some of us, our role is to provide empathy until the smarter guys come around.
PeterDA is just being modest BTW and like the others who caution they are not a medical professional is among the best at the advice they do offer, along with Tony, TallAllen and others.
At least at age 73, most of his medical costs are covered by Medicare.
You mentioned concern over the amount of time being spent by your local medical professionals, probably due to being in relatively remote area of country.
My advice would be to not let geography be a limiting factor. Seems you are within striking distance of Nashville, and could explore options at Vandy.
I am in west central Florida and not that familair with practictioners in your area, but assume Atlanta would offer more care giver choices too.
There are plenty of posters on this forum familiar with good doctors in KY, TN, GA etc.
Your dad is lucky to have your loving support and those of us on the forum will pray for his and your continued well being.
