Today is day 5 since the surgery. My facial swelling went down from day 3 to 4, but increased today. The right bottom side of my face is in more pain than yesterday, but not bad enough to need pain medicine. Last night when I pushed around in the area (I know, big mistake) it looked like a white-ish ooze or puss came out. Today there is a white/ yellow/ gray slimy cover sitting over the extraction site (see picture). Is this normal or does this look infected?
