Is extreme and prolonged swelling of the labia after a median thigh lift normal? Will anything reduce the swelling?

Ihad a medial thigh lift 15 days ago, and experienced extreme swelling of the labia, which my surgeon said would reduce to normal in a week or so. However, I'm still unable to walk, sit, or even stand for long because the swelling makes these activities very painful. I haven't read of anyone else complaining of this; is this usual? If so, how long is it likely to last? And most importantly - what can I do for some relief?
