Hi Im Mel Im 6'4, 175lbs, Have No Medical History.

Hi im Mel im 6'4, 175lbs, have no medical history. I have been punched very hard to my upper right cheek bone, it swelled up in late Aug of this year and I put ice on it immediately 20 mins on and off for 24 hours, i went to the doctor but did not want to take a CT scan if it wasnt to serious of a issue, right now the swelling has subsided but I still see a little lump when I look to my right at my appearence in the mirror. I'm thinking that its just soft tissue that have not healed fully yet but I'm trying to understand why is it taking so long to heal. At times it can feel tender but then it can feel like nothing at all. Also the tissue feel like its sinking down a little from underneath my eye. Is there any great advice u can give me to heal up faster?
