What is the biology of a headache?

Question

What is actually happening when a person experiences a headache? I have been getting them frequently and am just curious.

Answer 1

A headache (medically known as cephalalgia, sometimes spelled as cephalgia) is a condition of pain in the head; sometimes neck or upper back pain may also be interpreted as a headache. It ranks amongst the most common local pain complaints.

Headaches have a wide variety of causes, ranging from eye strain, sinusitis, migraine and tension to life-threatening conditions such as encephalitis, meningitis, cerebral aneurysms and brain tumors (although more than 95% of headaches are not life-threatening). When the headache occurs in conjunction with a head injury the cause is usually quite evident; however, many causes are more unclear. The most common type of headache is a tension headache. Some experience headaches when dehydrated, or suffering from caffeine withdrawal symptoms.

Treatment of uncomplicated headache is usually symptomatic with over-the-counter painkillers such as aspirin, paracetamol (acetaminophen) or ibuprofen, although some specific forms of headaches (e.g. migraine) may demand other, more suitable treatment, usually triptans.
