Thanks Ron, Daves' kidney's thankfully are the only parts affected though the Odema he has with it is in both feet, legs, chest, stomach, neck, face, hands and arms.Because of this he can only walk a few steps at a time and due to low blood pressure that comes with his fluid retention and now also his meds, he nearly collapses when changing to a standing position..he is very depressed. We've been together for nearly 25 years and he hardly ever got sick and now whamo.Poor bloke.
