"My question is I did Efudex for 12 days on my face! There was some blisters and redness around my nose and my lips. Since I have stopped the treatment is it now spreading to my cheeks and chin. Is it normal to get worse and spread after you stop the treatment? I am applying an ointment of poly spirit with a freezing agent but that wears off in approx 30 min. Has anyone else had it spreading after stopping treatment and how long will this continue?"
