question: I had all four wisdom teeth removed 5 days ago. I no longer have any pain from the surgery. All of the swelling has gone down except for a huge golf ball size lump that developed in my lower left cheek. The lump is "heavy", hard, and tender to the touch. Teeth and gums seemed to have healed up just fine. What is this huge lump? It is causing much discomfort. How do I get the swelling to go down and knot to dissolve??
