1 month ago a man punched my face. Much swelling on left cheek. I didn't ice it as much as I should've. Swelling is reduced but still there. Will my face ever return exactly back to the way it was before being punched? Will icing it now still help?

If its STILL swollen after a month then you likely have a cracked/broken bone.  Eventually the swelling will decrease but the bone will have to mend first.  You may want to get an xray to make sure the bone wasnt deformed in a way that threatens your eye and needs resetting.
