Types of headache

Headache is one of the most common health problems that affects most people at one time or another.

Headache

A headache is pain or discomfort in the head, scalp, or neck. Serious causes of headaches are rare. Most people with headaches can feel much better by making lifestyle changes, learning ways to relax, and sometimes by taking medicines. 

Causes

There can be many causes of a headache such as physiological changes in the head, constriction of blood vessels, abnormal neuron activity, genetic causes, excessive smoking, excessive drinking, lack of water in the body, oversleeping, overuse of pain killers, eye strain, neck strain, and others.
Headaches can be classified into three main categories: tension headaches, migraine headaches and cluster headaches.

• tension headache: 

1. The most common type of headache is tension headache. It is likely caused by tight muscles in your shoulders, neck, scalp, and jaw.
2. May be related to stress, depression, anxiety, a head injury, or holding your head and neck in an abnormal position.
3. Tends to be on both sides of your head. It often starts at the back of the head and spreads forward. The pain may feel dull or squeezing, like a tight band or vice. Your shoulders, neck, or jaw may feel tight or sore. 

• migraine headache :

1. involves severe pain. It usually occurs with other symptoms, such as vision changes, sensitivity to sound or light, or nausea.
2. The pain may be throbbing, pounding, or pulsating. It tends to begin on one side of your head. It may spread to both sides.
3. The headache may be associated with an aura. This is a group of warning symptoms that start before your headache. The pain usually gets worse as you try to move around.
4. Migraines may be triggered by foods, such as chocolate, certain cheeses, or mono sodium gluta mate (MSG). Caffeine withdrawal, lack of sleep, and alcohol may also be triggers. 

• Cluster headache :

1. is a sharp, very painful headache that occurs daily, sometimes up to several times a day for months. It then goes away for weeks to months.
