Pain on the left side of the back of the head, if the patient is accompanied by coughing, sneezing, runny nose and other symptoms, should be considered to be caused by a cold, possibly the left side of the occipital neuralgia. In this case, the neuropathic headache will be aggravated when the patient walks or sneezes, coughs, or goes upstairs, and the pain is mainly throbbing like an attack, or cutting like a pain. The main treatment is to take oral pain relievers to relieve the headache, such as pain relieving tablets or aminogest, and also to take Chinese medicine such as Chuanxiong Chajiao San and Du Liang Dripping Pills to dispel wind and cold and relieve the headache. The pain on the left side of the back of the head is also on the side of the brain and is episodic in nature, often triggered by exertion, poor rest or emotional excitement. It may be accompanied by aura before the attack, such as blurred vision, etc. You can take Zolmitriptan tablets to relieve migraine attacks.
