Should I go to emergency room....I had biopsy of lower right gum this past Wednesday. Now I have significant swelling of area under the gum on lower right side of jawline and under my chin, with much pain. I can barely swallow as it hurts and tongue is painful, as well. I have been taking percocet (generic), Advil, and Tylenol, but with little alleviation of pain. But the swelling continues to get worse.
