This article explores tension headache symptoms and the complications that may arise if the headache becomes chronic.

A tension headache may feel like you are wearing a tight headband or an extra-small baseball cap.

Some people even describe it as feeling like their head is in a vise.

While unpleasant and nagging, tension headaches are not dangerous.

Other possible symptoms of tension headaches are light sensitivity (photophobia) or sound sensitivity, but not both.

They are more common in women and may last hours or be continuous.

Note that Verywell Health prefers to use inclusive terms.

But when citing research, the terms for gender and sex from that source are used.

A healthcare provider may also look for pericranial tenderness if a tension headache is suspected.

Complications

Headache complications are health issues that can arise from an underlying headache disorder.

While tension headaches can undoubtedly be a nuisance, the good news is that they are not medically harmful.

Tension headaches are also not generally disabling unless they occur frequently.

With frequent or chronic tension headaches, individuals may experience a poorer quality of life or increased stress.

They may also miss more days at work or have reduced work efficiency.

Individuals with chronic tension headaches are also at increased risk formood disorders, especially anxiety and depression.

They may also be more likely to experience anger and emotional distress.

In rare instances, though, a headache can be the first or only sign of another health condition.

Light or sound sensitivity can also be present.

Tension headaches, while nagging and unpleasant, are not usually debilitating, unless they become chronic.
