Most people describe a tension headache as a feeling of a tight band or dull ache around the head or behind the eyes. A common cause of tension headaches is subluxations in the upper back and neck.
Headaches affect just about everyone at some point and they can present themselves in many different ways. Some people only experience pain in one part of their head or behind their eyes, some people experience a pounding sensation inside their whole head, and some people even experience nausea, while others do not. The pain itself may be dull or sharp and may last for anywhere from a few minutes to a few day
Although headaches can be due to a wide variety of causes, such as drug reactions, temporomandibular joint dysfunction (TMJ), tightness in the neck muscles, low blood sugar, high blood pressure, stress and fatigue, the majority of recurrent headaches are of two types: tension headaches (also called cervicogenic headaches) and migraine headaches
Tension type headaches are the most common, affecting upwards of 75% of all headache sufferers. Most people describe a tension headache as a constant dull, achy feeling either on one side or both sides of the head, often described as a feeling of a tight band or dull ache around the head or behind the eyes. These headaches usually begin slowly and gradually and can last for minutes or days, and tend to begin in the middle or toward the end of the day. Tension headaches are often the result of stress or bad posture, which stresses the spine and muscles in the upper back and neck.
Migraine headaches are caused by a constriction of the blood vessels in the brain, followed by a dilation of blood vessels. During the constriction of the blood vessels there is a decrease in blood flow, which is what leads to the visual symptoms that many people experience. Even in people who don't experience the classic migraine aura, most of them can tell that an attack is immanent. Once the blood vessels dilate, there is a rapid increase in blood pressure inside the head. It is this increased pressure that leads to the pounding headache. Each time the heart beats it sends another shock wave through the carotid arteries in the neck up into the brain.
Chiropractic and headaches
Each individual's case is different and requires a thorough evaluation before a proper course of chiropractic care can be determined. However, in most cases of tension headaches, significant improvement is accomplished through manipulation of the upper two cervical vertebrae, coupled with adjustments to the junction between the cervical and thoracic spine. This is also helpful in most cases of migraine headaches, as long as food and lifestyle triggers are avoided as well.
