What Is The Treatment For Cellulitis Of The Lower Leg And Red Patches In The Ankle?

I was diagnosed with cellulitis of the lower leg, two weeks' ago. I spent one week in hospital on IV antibiotics and a further week at home on antibiotic pills. The swelling has gone down, there is a small patch of redness but the ankle is still a little puffy. I would like to take a short flight next week (2 hours). Is there any problem with doing this?
