Muscle tension headaches, or â€œstress headachesâ€ make up 90% of all headaches. They occur frequently and are often worse in the afternoon or early evening. The pain is usually on both sides of the head, often at the base of the neck or above the eyes.
The trigger points commonly stem from: the top of the shoulders (upper trapezius), the back of the head (suboccipitals), and the back of the neck and top of the shoulders (levator scapula). The headaches usually last for days or weeks.
