What is half a headache?

How to judge the cause of pain in half of the head needs to be judged based on the specific location, nature of the pain and whether there are other accompanying symptoms. First, if the pain is severe and fluctuating, that is, jumping pain, and repeated attacks. For example, aura such as blurred vision, then this headache is very likely to be a migraine. Second, if the pain on one side is a pinprick or lightning-like attack and stops suddenly, then trigeminal neuralgia is more likely; third, if the pain is dull and accompanied by nausea and vomiting, then the possibility of brain tumor cannot be ruled out. Therefore, no matter what the cause of headache, should go to the neurology department of the regular hospital, let the doctor according to the symptoms, signs and brain CT, or brain MRI examination results to judge the specific cause, targeted treatment.
