A tension headache is generally a diffuse, mild to moderate pain that's often described as feeling like a tight band around your head. A tension headache — or tension-type headache as it's medically known — is the most common type of headache, and yet its causes aren't well understood.
It may feel as if muscle contractions are responsible for your head pain, which is why this type of headache is generally referred to as a tension-type headache, though experts no longer think muscle contractions are the cause.
Fortunately, effective treatments for tension headaches are available. Managing a tension headache is often a balance between fostering healthy habits, finding effective nondrug treatments and using medications appropriately.
