Tension headaches usually affect both sides of the head and last from thirty minutes to several days or more.
TTH are by far the most common type of chronic headache. People who experience migraines typically also have tension headaches in between their migraines these are also known as transformed headaches.
Symptoms of TTH
Tension headaches usually affect both sides of the head and last from thirty minutes to several days or more. They often have a characteristic tight-band or vice like pain with a ‘dull steady aching’ quality. Symptoms can vary in intensity from mild to moderate to severe; they may also affect sleep. They are not accompanied by the additional symptoms that traditionally distinguish migraine headaches such as light sensitivity (photophobia), and flashes and patterns in the eyes (visual scotoma).
Tension headaches are said to affect about 1.4 billion people (20.8% of the population) and are more common in women than men (estimated at 23% to 18% respectively).
TTH and trigger points
Muscular problems and tension are commonly associated with TTH and trigger points within muscles may either be causative or may perpetuate TTH. The most commonly affected muscles are Trapezius, Sternocleidomastoid, Temporalis, Masseter and Occipitofrontalis. There is also a strong association with postural issues such as the upper crossed pattern. The pain processing part of the central nervous system is almost certainly involved in TTH as it shows up abnormal in scans.
Trigger points often add to the misery of headaches because they are associated with peripheral and central sensitization. Long-term inputs from trigger points may lead to a vicious cycle that converts periodic headaches into chronic tension headaches. In such cases even if the original initiating factor is eliminated, the trigger point-central sensitization cycle can perpetuate or even worsen.
TTH's are often aggravated by stress, anxiety, depression, fatigue, noise, and glare, but they can also be associated with neck arthritis or neck disc problems.
Acute or Chronic
TTH headaches can be episodic or chronic. Episodic tension-type headaches are defined as tension-type headaches occurring fewer than 15 days a month, whereas chronic tension headaches occur 15 days or more a month for at least 6 months. Headaches can last from minutes to days, months or even years, though a typical tension headache lasts 4–6 hours.
Fact File - Seven Main Causes of Tension Type Headaches:
Stress: usually occurs in the afternoon after long stressful work hours
Uncomfortable stressful position and/or bad posture
Irregular meal time (hunger is reported in up to 50% of people)
Tooth Clenching (bruxism)
