My maternal grandfather had knee replacement surgery November 6th. Everything went very well and he came home that weekend (he had the surgery in Nashville, about 2 hours away from Sparta). He was doing okay, but had some issues. Today I got a call from my mom, and he has renal failure. My mom and Nannie took him back to Nashville. After a LONG wait in the ER he is now admitted. Right now we don't know much. We do know that his kidneys are not working and he is in renal failure. We are just praying for God to give the doctors wisdom to help him, and for healing of his kidneys.
