Is On And Off Painful Bony Knot Due To Hard Blow To Back Of Head Normal?

Can a bony knot, caused by a hard blow to the back of the head...come and go with pain, over the course of a year? There was no bleeding, and the knot was present right after the injury, but went away after about a month; periodically, it reappears for a week or two, then goes away? Is this normal?

Bump after injury is formed due to collection of blood in scalp. But after resolving it should not reappear. I would suggest you to show to a surgeon if every thing is normal. Though it is not an emergency.
