Thanks for writing in.
The huge bump / pain is usually haematoma
(blood collection). Since you are improving & there is decrease in pain & swelling, nothing to do at present. If your skin is normal, then you can apply hot fomentation, which will aid in decreasing the swelling. A course of over counter pain killers like ibrufen twice a day for 3 days will decrease your pain.
Since blood supply to face & head is high, healing will also be faster with better results. Just wait & watch. If you develop any other signs or symptoms like giddiness, persistent headache, confusions etc.. then it warrants an urgent medical examination.
Get well soon,
