Nerve pain at the back and left side of the head is caused by late nights, exertion, mood swings, smoking, and alcohol consumption, and is attributed to the occipital or temporal nerves. When these triggers appear, patients who are physically weak or who usually have migraine headaches will be induced to relapse and the nerve pain will reappear. In this case, the first thing to do is to avoid the triggers, standardize the time of rising and lying down, quit smoking and drinking, and especially pay attention to good emotional regulation. If the symptoms of pain are obvious, you can take western painkillers, such as Migrainin or ergotamine tablets, ibuprofen granules and so on. The treatment of neurological headache with Chinese medicine is very effective, however, it needs to be analyzed according to the specific tongue and pulse. Acupuncture is also very effective and can significantly relieve pain attacks.
