What causes a dull headache at the back of the head due to cold exposure, and what should be done about it?

Occasional dull pain in the back of the head due to cold exposure may result from physiological causes, or could be triggered by pathological conditions such as migraines or upper respiratory tract infections. Symptoms can be improved through physical therapy or medication. Specific analysis is as follows:

I. Physiological Causes

Cold exposure to the back of the head may cause cerebral blood vessel spasm and constriction, leading to ischemia and hypoxia in brain tissue, which manifests as a dull ache. This type of pain usually gradually improves with heat application or massage.

II. Pathological Causes

1. Migraine

Migraine can be influenced by factors such as genetics, stress, or emotional strain. During an attack, extracranial arteries may dilate, causing symptoms as described. In such cases, it is recommended to follow medical advice and use medications such as celecoxib capsules, acetaminophen tablets, or sumatriptan succinate tablets to alleviate symptoms.

2. Upper Respiratory Tract Infection

Upper respiratory tract infections may be caused by bacterial or viral infections, low immunity, and other factors. Inflammatory mediators may enter the intracranial circulation, triggering such headaches, often accompanied by symptoms like coughing and nasal congestion. Patients may take appropriate medications under medical guidance, such as penicillin V potassium tablets, amoxicillin capsules, or cefixime dispersible tablets, to help relieve symptoms.

In addition, this condition could also be caused by cervical spondylosis, hypertension, cerebral infarction, or other conditions. It is important to seek timely medical evaluation and actively cooperate with treatment.
