Or due to cerebrovascular inflammation, such as temporal arteritis and other stimulation of the nerves, the above symptoms may also appear.
2. Intracranial infection: such as viral meningitis, bacterial meningitis and other diseases, due to infectious factors leading to intracranial edema, increased cranial pressure, may also appear left headache symptoms.
3. Intracranial tumor: such as meningioma, glioma and so on. Increased cranial pressure caused by tumor occupying lesions may lead to left-sided headache. It is persistent swelling pain, or accompanied by nausea and vomiting.
4. Migraine: the onset of this disease may cause pain in one or both temples, which is throbbing and intensifies in paroxysm, accompanied by nausea, vomiting, and sensitive to sound and light.
