Let’s take a closer look at the causes of various headaches.

1. Physical and chemical factors

Headaches are caused by compression, traction, stretching, displacement, etc. of pain-causing tissues inside and outside the skull due to inflammation, injury, or tumors.

(1) Headache caused by compression, traction, stretching or displacement of blood vessels

It is common in intracranial space-occupying lesions: such as tumors, abscesses, hematomas, etc., which cause compression, traction, stretching or displacement of blood vessels; increased intracranial pressure and intracranial hypotension, etc.

(II) Headaches caused by dilation of intracranial and extracranial arteries due to various reasons

(III) Chemical stimulation of the meninges

Bacterial meningitis, viral meningitis, other biological infectious meningitis, etc.

(iv) Prolonged contraction of the head and neck muscles

Such as continuous contraction of the head and neck muscles, and reflex tension contraction of the neck muscles caused by neck diseases, such as cervical spondylosis and neck trauma.

(V) Compression or inflammation of cranial nerves, cervical nerves and ganglia

Common causes include trigeminal neuritis, occipital neuritis, tumor compression, etc.

(VI) Lesions in the eyes, ears, nose, paranasal sinuses, teeth, etc.
