The pain on the left side of the brain may be caused by organic lesions on the left side of the brain, or may be caused by organic lesions on the left side of the brain. Intracranial organic lesions can be seen in brain tumors and parasitic infections in the brain. If the patient has encephalitis or cerebral hemorrhage, it may also show some corresponding symptoms and signs. Patients with encephalitis may show fever or meningeal irritation. If cerebrovascular disease is considered, it is usually acute onset. Craniocerebral tumors are mostly chronic onset, and may show some physical symptoms, including limb weakness and sensory disturbance. If necessary, check brain MRI and EEG. If the patient is extracranial organic disease, it can be seen in otitis media, gingivitis or sinusitis. Glaucoma patients can also show.
