I had an extended medial thigh lift on March 20 (35 days ago) and of course I expected swelling but why is my left foot/ankle swelling at least 80% more than the right? I am spending at least ~15 hours a day with my legs elevated above my heart. A examination was made to see if it was a DVT, results came back negative. Doctor says my lympathic system is disturbed from the surgery, but he didn't offer any recovery suggestions. How long will this last and what can I do?
