Head injury leading to something more serious? - head injury more condition_symptoms

When I was younger, I was on the head with a mallet to beat and made me bleed a lot, do not go to the hospital because my parents got to know later, but now I'm very bad headache when I was there. Is there a connection between the two? Thank you.

Oh, and it was 7 years ago, when I hit on the head.
