This is Dr. David
swollen ankles can be caused by many causes such as poor circulation in the legs
from diabetes or
new heart weakness causing congestive heart failure which can back up fluid in the legs and in the lungs (which can cause difficulty breathing)
or a weak liver which is not making enough blood protein called albumin can cause swelling in the legs.
the compression stocks are just one way to help squeeze fluid up and out of the legs.
do you have any history of heart problems?
or liver weakness or poor circulation in the legs?
