Husbands Legs And Feet Are Extremely Swollen. He Had A

Husbands legs and feet are extremely swollen. He had a stroke seven years ago affecting his left side which is paralyzed....he had another stroke in December resulting in aphasia. He is taking 40 mg. of lasex
But swelling is often very sever. Dr. Says just elevate as much as possible. He is very sedentary although he does do therapy each morning. His cardiologist seems to think this is par for the course. He also has a fib. Thanks for your suggestions.
