There are many causes of right posterior cerebral pain, and the common causes are mainly the following: 1. Migraine, mostly seen in patients with high mental stress, work and rest disorders, and frequent late nights, mainly manifests as paroxysmal pain in the temporal region on one or both sides. The symptoms can be relieved by taking flunarizine capsules and tianma headache tablets. 2. Occipital neuralgia, mostly caused by viral attack, is mainly manifested as paroxysmal needle-like pain in the posterior occipital area, which lasts for several seconds to tens of seconds, generally not more than one minute. It can be treated with gabapentin for pain relief, and can also be treated with nerve-nourishing drugs such as adenosine cobalamin and methylcobalamin. 3. Cerebrovascular diseases, such as cerebral hemorrhage and large cerebral infarction, can cause an increase in intracranial pressure, resulting in severe headache, often accompanied by jet vomiting. It is necessary to improve the head-related examination to clarify the specific diagnosis and then carry out targeted treatment.
