question: I have been given Sulfam+tri for swollen ankle after skin graft for skin cancer.  Surgery on Aug. 16th and doing fine but after a day of unusual walking (house guest!) my ankle swelled hugely and a deep rosy red.  I have kept it up for 3 days and better.  Called Dr. yesterday because still swollen and red altho somewhat better.  SULFAM=TRI TB 800/160MG.   Your opinion, please
