You had no fever right? I think your only problem was the swelling that caused you a lot of pain. The pain fades with the swelling so if you have not found anything abnormal in the coming days then, you'll be okay.
Hi adam224 , sorry to hear about your mishap , you must have taken a bad knock ,
Keep an eye on it , you say it's going down the swelling , give it a week you should be ok , Merry Xmas , Take care ,
