Hi,
It would be necessary that you be examined by a physician. Considering the fact that you are conscious, oriented in space and time and have no neurological deficit suggests that you are very likely to be in very good shape.
However, persistence of throbbing headache and stiff neck could be early signs of traumatic injury and a meningeal hemorrage. Consulting a physician to evaluate your health status and prescribe an analgesic is important.
While waiting, if you notice an increase in the intensity of headache, visual abnormalities, jet like vomiiting or fatigue and altered mental status, this could indicate an increase in the intracranial hypertensin, which is a neurological and neurosurgical emergency.
Reporting to the emergency should be done i this case immediately for a CT scan to be done. If not, consult your doctor for a normal and usual follow up.
Thanks so much as I pray this helps,
Best regards,

Hello, thanks for using HCM.
Head traumas are generally dreaded situations because even if the person appears fine after the trauma complications can still arise months later regardless of initial loss of consciousness or not. Headache which is increasing in intensity, LOB and dizziness are symptoms that could indicate a probable on going intracranial process such as a growing hematoma or cerebral edema. Stiff neck in a context of trauma would most probable indicate irritation of the meninges from meningeal hemorrhage. Symptoms such as projectile vomiting, increasing headache, progressive weakness of a limb or limbs and progressive alteration of consciousness are indicative of a serious intracranial process going on and should prompt immediate consultation with a neurosurgeon.
With the series of symptoms, first throbbing headed , accompanied one day later by stiff neck and then LOB and dizziness, it is imperative you see a neurosurgeon for an evaluation and a CT scan to rule out any on going intracranial process and for eventual follow up.
