Almost 3 weeks ago, I was cutting down an ash tree & got a slap from a branch on my cheekbone. There was major swelling & bruising of my face & pain of my cheekbone. There was clear nasal drip. Since then, the swelling has gone down on my face, most of the brusing has gone except over the cheekbone which still seems to be blacker some days. My concern is my cheekbone is still swollen, hard to the touch & obviously tender. This far on, is this swelling par for the course or does it require medical attention?
