Hubby came home yesterday and decided to walk around a fair bit as he wants to do what they tell him. Today he was running a fever due to a bladder infection he developed in the hospital. They sent him home anyway but family doctor prescribed cipro and the burning sensation has disappeared already with fever going down slowly. However today he is weak and visibly shaking at times. He thinks he should still try to walk. I think he needs to rest and get over the fever. He is afraid that will set back recovery and lead to scar tissue. Any opinions from those who have gone through this?
