Fell Down Steps Three Weeks Ago This Coming Saturday. My

Fell down steps three weeks ago this coming Saturday. My foot slipped off the edge of one step and I dropped and slid down two more. It left me bruised from my thigh all the way across the left cheek. The bruising has finally almost vanished but there's still swelling on the left cheek just slightly below the waistline. It isn't painful but tender and only when putting all the pressure on that side when sitting on certain surfaces, getting into a car, or laying on that side in bed.
