i had my wisdom teeth removed a week ago, my mouth swelled to the size of a tennis ball so i went back to the dentist 3 days later and got antibiotics to help the swelling, now there is pus coming out from where my bottom wisdom tooth was removed and a hard tender spot of my cheek where if u press it very painful and forces pus out of the area where my wisdom tooth was, is this normal and what do i do about it, thanks
