[|Human|] I have swelling from my knees down with the worst being ankle and foot. I also have pain with worsening as the day progresses. I have been diagnosed with lymphedema and have a machine to help with that but it is not helping. I have already had a stress test and it was normal. What could be the cause of this?
[|AI|]  Welcome to Chat Doctor I have gone through your query and understand your concern. There are many causes of generalized swelling, but most common of this is congestive cardiac failure in which heart is not able to pump the blood efficiently. Second is low blood protein count. Other cause such as kidney failure and thyroid function should be excluded by kidney function test and thyroid function test respectively. You can discuss with your doctor about it. Hope your query get answered. If you have any clarification then don't hesitate to write to us. I will be happy to help you. Wishing you a good health. Take care.
