Most people do not take neck pain seriously. While it is uncomfortable, people attribute it to lifestyle factors like incorrect sitting posture or looking at their phones for too long. However, extended periods of neck pain could be serious. Most neck pains do not need to be treated as a serious medical threat, however there is an exception. Harvard Health Publishing explains that there's a rare problem worth knowing about: a tear in one of the blood vessels in your neck. Doctors call this cervical artery dissection. It doesn't happen very often – only to about two people out of every 100,000 each year. However, it's a leading cause of strokes in people younger than 50, which makes it important for awareness. What Is Cervical Artery Tear? In your neck, there are two sets of important blood vessels: the carotid arteries and the vertebral arteries. Together, these are called the cervical arteries, and they carry blood to your brain. A cervical artery dissection is when there's a tear in the inner lining of one of these blood vessels. When a tear happens in a cervical artery, blood can leak in between the layers of the artery wall. This leaking blood can form a blood clot. This clot can either completely block the flow of blood through the artery or break off and travel to an artery in the brain. If either of these things happens, it can cause a stroke, which is a serious medical emergency. Who Should Be Careful? Cervical artery tears happen more often in younger adults for a couple of reasons. First, some people are born with weak connective tissue in their bodies, which can make their arteries more likely to tear. For these people, a tear in a neck artery is more likely to happen when they are younger. In older people, strokes are often caused by other things, like the arteries in the brain getting narrow because of fatty buildup. But it's still possible for older people to have cervical artery dissections. One study found that some people diagnosed with this problem were over 60. The second, and maybe a bigger reason why these artery tears are more common in people under 50 is that younger adults are more likely to do activities that involve neck movements that can sometimes cause a tear. There have been reports of dissections happening after things like heavy weightlifting, dancing with a lot of head movements, and even yoga. If certain yoga poses, like a shoulder stand, aren't done correctly, they can bend the neck too far backwards. You can also bend your neck too far back when you're getting your hair washed at the sink in a hair salon. Even though it doesn't happen very often, there's even a name for it: "beauty parlor stroke syndrome." To be safe, you can ask your hairdresser for a neck extension, which is a little cushion that supports your head so your neck doesn't have to bend so much. Watch Out for Unusual Neck Pain If you have a cervical artery dissection, the neck pain is often different from regular neck pain. It might feel strange, it doesn't go away, and it's often joined by a really bad headache. If the tear is in the carotid artery, the pain might spread along the side of your neck and up towards the outside corner of your eye. If it's in the vertebral artery, it might feel like something sharp is stuck at the base of your skull. If you have this kind of pain, especially if you also have stroke symptoms like dizziness, seeing double, jerky eye movements, feeling unsteady when you walk, or slurred speech, it's important to get medical help right away.
