Your neck moves a lot and is not protected by other parts of your body, so it’s prone to injury or strain. Pain can occur on either side of your neck. It may be related to simple muscle strain, or to more serious conditions like nerve damage or spinal injury.

The neck connects to several other parts of the body. For this reason, neck pain can lead to pain in other areas of your body, including your shoulders, arms, back, jaw, or head.

Neck pain on the right or left side of your neck may go away on its own, or with home-based treatments, after a few days or weeks. You should see a doctor if you have chronic or severe neck pain.

What causes pain in the right side of the neck?

Some causes of neck pain include:

Muscle strain

You may notice that your neck hurts after using a computer or smartphone for an extended period of time. You may also experience pain in the neck after driving long distances or engaging in work or hobbies that restrict head movement for prolonged periods.

These actions can cause the muscles in your neck to weaken. If your neck muscles are weak, your neck joint may become stiff and you may have difficulty moving your neck. A stiffened neck joint may contact nerves or muscles when rotating, resulting in pain.

Poor sleeping position

Your neck may hurt after sleeping in an unusual position. You may be more likely to experience neck pain if you sleep on your stomach. Sleeping with too many pillows can also cause neck pain because your head and neck are not in line with the rest of your body.

Also, your mattress may be too soft and cause the alignment between your head and neck to be off compared to the rest of your body.

Bad posture

Posture is important to preventing, reducing, or eliminating neck pain. Poor posture directly affects the muscles near your neck and shoulders as well as your spine.

The longer you maintain poor posture, the weaker these parts of your body become, leading to more pain.

Anxiety or stress

Experiencing anxiety or stress can lead to your muscles tightening. You may especially feel this around your neck and shoulders.

Whiplash

Trauma to the neck can cause a neck sprain, leading to pain. Whiplash is another term used for neck sprain. This occurs when your ligaments or muscles in the neck become injured because something impacts your body that causes your neck to overextend and snap back into place too quickly.

This type of impact can occur if you’re in a car accident. It may also occur in other instances like when riding a roller coaster or encountering a blunt force during a sports activity.

Brachial plexus injury

A brachial plexus injury can occur when you play contact sports or are in a traumatic accident. This can damage the brachial plexus, a set of nerves connecting your spine, shoulders, arms, and hands, resulting in neck pain.

Degenerative conditions

What is the outlook for pain in the right side of the neck?

Experiencing pain on the right side of your neck is not unusual and most likely not something to be concerned about. Neck pain often will go away on its own after a few days or weeks, particularly if you engage in self-care treatments and do not strain your neck further.

Severe neck pain that occurs after an accident or seemingly out of nowhere should be seen by a doctor, as well as neck pain linked to other serious symptoms.
