Facial Swelling

On 6/3/9 I had Pixel Skin Resurfacing.  Today 6/8/9 my face is so swollen I can barely see.  I went back to the doctor who performed the procedure this morning and he told me is is normal, but I had seen the worst he had ever seen.  He gave me a Dospak 21 to accelerate the reduction of the swelling.  He promised me this was not permanent.

Will this medication work?  How long will it take?

Thank you
