[|Human|] My father, age 90, has severe edema of his left foot. This condition has been ongoing for the last three weeks. At times, the swelling decreases. He says he has no pain. However, his usual response to any question regarding his health is that he is fine.
[|AI|]  Hi, thank you for providing the brief history of your father. As you mentioned the edema in ankles and no pain, it is assumed to me that the cardiac rehabilitation is needed. Since his age is 90, what happens in this age is the slowing of the venous return due to lack of sufficient mobility. For reducing the swelling, what can be helped in this age is to perform ankle toe movements to Improve the venous return. As also, exercises are highly recommended in geriatrics because what has to be understood here is the slowing for the metabolism and this leads to abnormal reactions in the body. Exercise, mild also will help improve the metabolism and cardio respiratory endurance. Which will help in future to avoid small issues like this. With the grace of God I wish your dad a long healthy life. RegardsJay In Chat Doctor.
