A throbbing pain on the left side of the head may be caused by trigeminal neuralgia, tension headache, intracranial lesions, migraine and other causes.
1. Trigeminal neuralgia: If the trigeminal nerve on the left side of the head is compressed by blood vessels causing its dysfunction, transient paroxysmal pain will occur in the area innervated by the trigeminal nerve, which can lead to a throbbing pain on the left side of the head.
2. Tension headache: due to excessive mental tension, sudden emotional excitement or excessive fatigue and other reasons, such as the left temporal blood vessel contraction, there will be a burst of throbbing pain on the left side of the head.
3. Intracranial lesions: If there is atherosclerosis, venous thrombosis or aneurysm in the left side of the head, the blood supply to the left side of the head is insufficient, and the brain tissue loses nutrient supply, which can trigger a throbbing pain in the left side of the head.
4. Migraine: manifested as throbbing pain on one side of the head, often accompanied by light sensitivity, nausea, vomiting and other symptoms.
If you have a throbbing pain on the left side of your head, you should go to a regular hospital in time to find out the cause of the problem and choose a suitable method of treatment under the guidance of a professional doctor.
