Intermittent pulsating pain on the left side of the head may result from normal physiological causes, or pathological conditions such as occipital neuralgia or migraine. Treatment options, including general management or medication, depend on the specific underlying cause. Details are as follows:

I. Physiological Causes

Mental stress, lack of sleep, and similar factors may lead to constriction of scalp arteries and involuntary contraction of neck muscles, causing unilateral throbbing headaches. Additionally, consuming excessively cold beverages or excessive alcohol intake may also trigger one-sided head pain. Symptoms can often be relieved through adequate rest and increased fluid intake.

II. Pathological Causes

1. Occipital Neuralgia

When the left greater occipital nerve is compressed due to bone spurs, tumors, or viral infections, it may cause pain in the area controlled by this nerve, including the occipital region and parts of the head, commonly manifesting as pain on the left side of the head. Medications such as diclofenac sodium sustained-release tablets or ibuprofen sustained-release capsules may be taken under medical guidance.

2. Migraine

A common neurovascular disorder that may arise from dysfunction in blood vessel dilation and constriction, characterized by episodic headaches, often accompanied by nausea and vomiting. Medications such as Toutongning Capsules or Compound Yangjiao Capsules may be used as directed by a physician.

In addition to the above common causes, other potential conditions include giant cell arteritis, upper respiratory tract infections, and herpes zoster. If discomfort occurs, prompt medical consultation and treatment are recommended.
