Hi there, I have an issue of swelling in my ankles and feet, I am 73 years old, in a power chair, do have Cerebral Palsy, and just transfer myself from power chair to recliner, or to the driver's seat in my handicapped accessible van. So most of the time I sit, but at times i need to get up as i do live alone, and very independent. So if you could lead me to what is really causing the swelling, this would be good, and thanks a head of time.
