DEAR DOCTOR K: Why are my legs and ankles swollen? What can I do about it?
DEAR READER: In yesterday's column, I answered the first part of your question. I explained the different causes of leg and ankle swelling (edema) -- some not serious, and others very serious. Today I'll explain what your doctor needs to do to diagnose the cause of the edema, and what you and your doctor can do to reduce the swelling.
