“Extremely Swollen After Cast Removed - California”

I have always wanted the hump removed from my nose. So on Nov.29th I had rhinoplasty for hump removal and to fix my right septum so I could breathe better! After surgery the pain wasnt too bad only had to take tylenol. The night before the cast removal (day 9) my eyes swelled up almost shut. Then when the removed my cast my nose was red and extremely swollen! It has been 2 days since and my swelling is still really bad that I cant go out in public. I look like a character from Avatar. The dr. gave me a steriod to take. Is this extreme swelling normal?? and when will get get better?
