[|AI|]  Hello ! I read you question and understand your concern. It is very common to have headache after head concussion or trauma. It may be caused by the muscle contractions in the scalp, or by an irritated occipital nerve from the trauma. I think that it will get better spontaneously. You don't have any other symptoms like gait problems or numbness in your limbs. This is an indicative sign that there is nothing wrong with you (like an intracranial hemorrhage for example). So I would recommend having some rest. There is a high risk after a head trauma to get in a serious condition if the trauma is repeated. For this reason it is very important to be careful for a month after trauma and to avoid possible other trauma. Regarding the headache I would recommend painkillers for some days. Hope to have been helpful! Greetings !
