Tired wizard

Hubby is ill. Coughing and tired with this cold. He came downstairs for tea and then went to stand up and fainted! He’s OK but he’s hurt his knee by landing on an oil heater. He wouldn’t let me call an ambulance and he’s gone back upstairs with a walking stick. He’s like a tired old wizard, not happy, but not in the mood for TLC. Don’t know what to do. I’ll take him a drink and a sandwich in a bit. All I can do is help if I can.
