Facial contouring (long curve + cortical fracture) swelling on the 5th day

It's the 5th day after surgery and the swelling is still very severe ㅜㅜ It seems like the swelling is getting worse as days go by..? Above all, the swelling of my lower lip is so severe that I can barely open my mouth, and if it gets stuck somewhere while eating, I can't see it, so I wash it off with water or the gargle the hospital gave me, but it may still remain. Also, my lips have become so big that they are all puffy, and there is a lot of swelling on my entire face. Even when I walk around, I wear a hat and a mask... I go for a lot of walks, but why doesn't the swelling go down? I eat pudding, seaweed soup, protein drinks, steamed eggs, bread, pumpkin porridge, and chicken porridge, but why does the swelling never seem to go down? ㅠㅠ Is it a problem if I fall asleep on the recliner sofa at an angle of 20 to 30 degrees around 1 or 2 at night?
