Tension headache & migraines

What are tension headaches and migraines?

A tension-type headache is the most common type of headache and the one we think of as a normal, everyday headache. It may feel like a constant ache that affects both sides of the head. You may also feel the neck muscles tighten and a feeling of pressure behind the eyes.

Tension-type headaches are known as primary headaches, which means they’re not caused by an underlying condition. Other primary headaches include cluster headaches and migraines.
