Have you been seen for this problem as yet?
Thank you for all the information.
A bump forming on the skull under the skin after an injury is usually a hematoma which should have most likely resolved by now as far as I am concerned.
So other causes should be considered and ruled out and one of them is a lipoma or a cyst under the skin.
Both of these are harmless conditions which are diagnosed on physical examination.
So I would recommend that you be seen to have the diagnosis confirmed and then proceed accordingly.
