The cause of pain in the back of the head.

If the patient presents with pain in the right side of the back of the head, these patients need to be investigated for cause. If the patient presents with hemorrhage in the right cerebellum, large infarction in the right cerebellum, space-occupying lesion in the right cerebellum, or trauma to the head, fracture of the occipital bone, and pain in the right greater occipital nerve, these patients may present with pain in the right side of the back of the head. It is recommended that such patients must see a doctor as soon as possible and actively identify the cause. Cranial CT or MRI examination can be improved to determine whether there are organic lesions in the skull. If these patients show fractures, especially comminuted fractures, surgery may be required.
