I visited Dad tonight. He was sitting in bed as if he had never had anything done!! He says he has no pain and no side effects from the anaesthetic. He has been out of bed for an hour this afternoon and the only down side is that he has a tempory numb lower leg from the femoral block he had whish meant he wasn't able to take any weight through that leg today. Hopefully it should resolve soon.
Mum and I are thankful because there was a risk because of all his other health issues.
Thank you for all your kind wishes!
