Hello.
A blunt trauma to the head should not be ignored. Even if you have not lost consciousness, you should get yourself evaluated by a Neurologist or a physician to rule out any internal injury.
Your headaches could also be related to any inner ear problems. It's a good idea to see a doctor and be sure there is nothing serious.
Regards
