Signs & symptoms

The nature of the headache depends on the type of headache you are experiencing. A headache can be described as being located on any part of the head, unilateral or bilateral, and of a stabbing, throbbing or dull nature. Certain types of headaches have accompanying symptoms like sensitivity to light and nausea. Note that there are signs that their presence, along with a headache, requires urgent medical examination: fever or a stiff neck, seizure, fainting or change of consciousness, head injury, a sudden weakness in one of the limbs, or a feeling that the pain is "the worst you've ever had in your life".


Diagnosis of the type and cause of the headache is based on a person’s medical history, symptoms, and physical and neurological examination. According to the doctor's suspicion, additional tests, such as brain CT or MRI scans, may be needed.


The treatment for a headache depends on the type of headache, its cause and its severity. For primary headaches, there are several medications for pain relief and prevention. In the case of secondary headaches, there may be a relief of symptoms once treating the underlying cause.
