question: Hi I got all four of my wisdoms surgically removed, it's been exactly a week since they've been removed, and three of them are healing perfectly and the stitches seem ready to fall off, except for one... the wound on my bottom-left side is still experiencing sharp pain, and when I went to feel it with my tongue, it feels like a piece of loose fat is over the wound. I get a weird taste in my mouth too... what could this be?
