Swollen Ankle - It just would not fade

    Hello All:

My dear friend's mother has  a swollen ankle, left one,  and just would not fade away. In fact it is growing. She is diabetic and has this condition for a few weeks. She did go on tread mill for mild exercise just before this episode. I believe that she has tried a few home remedies, such as turmeric wrap, Castor oil wrap. She is fine when she goes to sleep, but after she wakes up and walks a bit she gets the swelling. 

What can she do to get the swelling  down and eventually go away.  I know that doctors will only give her more medications. Are there any safe medications she can take?

Thank you.
