Most of the left head nerve twitching pains are scalp neuralgia, trigeminal neuralgia, vascular headache, etc., which can generally be treated by medication to relieve the symptoms. Common causes and treatments: 1. Scalp neuralgia: When patients have cold, cold and other reasons, it may trigger scalp neuralgia, which in turn leads to localized paroxysmal twitch-like pain in the superficial area of the head, and the duration of the attack is usually variable. The symptoms can be relieved by giving appropriate drugs such as Tianshu capsule, Tianma head wind spirit and carbamazepine; 2. Trigeminal neuralgia: When trigeminal neuralgia is triggered by abnormalities in the central nervous system or organic head lesions, paroxysmal severe pain will appear unilaterally on the corresponding face, usually not exceeding the midline of the face. Such patients can be treated with drugs such as carbamazepine and phenytoin sodium. 3. Vascular headache: also known as migraine, often manifests as paroxysmal, pulsating throbbing pain in the head bilaterally or unilaterally, with more triggering factors, such as fatigue, staying up late, female physiological period, and large mood swings. Opioids or non-specific pain medications can be given for treatment during attacks; 4. Occipital neuralgia: Occipital neuralgia is mostly due to labor injury, inflammation and other causes of occipital nerve irritation, causing pain at the top of the occipital area. Occipital neuralgia usually manifests as unilateral persistent or paroxysmal stabbing pain, which can be treated by oral medication (such as non-steroidal anti-inflammatory drugs, anti-epileptic drugs, muscle relaxants, etc.) under the guidance of a doctor, and if it is secondary to occipital neuralgia, the primary cause should be actively treated to relieve the symptoms. Note: Patients with left head nerve twitching pain should pay attention to daily conditioning, maintain regular work and rest, eat a light diet and reduce stimulating factors to avoid triggering headaches.
