History
Pain onset in tension-type headache can have a throbbing quality and is usually more gradual than onset in migraines. Compared with migraines, tension-type headaches are more variable in duration, more constant in quality, and less severe.
IHS diagnostic criteria for tension-type headaches states that two of the following characteristics must be present: [1]
-
Pressing or tightening (nonpulsatile quality)
-
Frontal-occipital location
-
Bilateral - Mild/moderate intensity
-
Not aggravated by physical activity
Tension-type headache history is as follows:
-
Duration of 30 minutes to 7 days
-
No nausea or vomiting (anorexia may occur) [11]
-
Photophobia and/or phonophobia [11]
-
Minimum of 10 previous headache episodes; [11] fewer than 180 days per year with headache to be considered "infrequent"
-
Bilateral and occipitonuchal or bifrontal pain
-
Pain described as "fullness, tightness/squeezing, pressure," or "bandlike/viselike"
-
May occur acutely under emotional distress or intense worry
-
Insomnia
-
Often present upon rising or shortly thereafter
-
Muscular tightness or stiffness in neck, occipital, and frontal regions
-
Duration of more than 5 years in 75% of patients with chronic headaches
-
Difficulty concentrating
-
No prodrome
New headache onset in elderly patients should suggest etiologies other than tension headache.
Physical Examination
The physical examination serves mainly to exclude the possibility of other headache causes.
-
Vital signs should be normal.
-
Normal neurologic examination
-
Tenderness may be elicited in the scalp or neck, but no other positive physical exam findings should be noted.
-
Pain should not be elicited over temporal arteries or positive trigger zones.
-
Some patients with occipital tension headaches may be very tender when upper cervical muscles are palpated.
-
Pain associated with neck flexion and stretching of paracervical muscles must be distinguished from nuchal rigidity associated with meningeal irritation.
Complications
Complications of headache may include the following:
-
Overreliance on nonprescription caffeine-containing analgesics
-
Dependence on/addiction to narcotic analgesics
-
GI bleed from use of NSAIDs
-
Risk of epilepsy 4 times greater than that of the general population
-
Medication overuse headache
