Trapped Nerve? Postural Pain? - Understanding Your Neck Pain

What’s Really Going On?

Neck pain is rarely as simple as it feels.

For some, it starts after a poor night’s sleep. For others, it builds gradually from long hours at a desk. Sometimes it feels like tight muscles… sometimes like a “trapped nerve”… and sometimes it’s just a persistent stiffness that won’t resolve.

The reality is that neck pain is often multifactorial, meaning there is rarely a single cause. Instead, it tends to be influenced by a combination of factors including old injuries, muscle function, joint mechanics, stress, and daily movement habits (Sterling et al., 2019).

The role of modern posture

One of the most significant contributors to neck pain today is forward head posture, often referred to as “tech neck”. This occurs when the head gradually shifts forward relative to the shoulders — a position commonly adopted during prolonged use of phones, laptops, screens . Research has shown that this posture alters muscle activity and increases strain on the cervical spine (Damasceno et al., 2018; Palomeque-del-Cerro et al., 2020). Over time, this sustained position changes how load is distributed through the neck, increasing mechanical stress on passive structures such as joints and ligaments.

Facet joints: a key piece of the puzzle

At the back of each vertebra sit small joints known as facet joints.

These joints:

• Guide and control movement

• Provide stability to the spine

• Help distribute load between vertebrae

They are also highly innervated, making them particularly sensitive to mechanical stress and irritation (Sterling et al., 2019).

When posture shifts forward:

• Compressive forces increase through the posterior cervical spine

• The natural cervical curve (lordosis) is reduced

• Repetitive loading is transferred onto the facet joints

Biomechanical research shows that these joints are vulnerable to compression and altered loading patterns, which can contribute to irritation and pain over time (Stemper and Yoganandan, 2019).

The muscle link: where most problems begin

Facet joint irritation is rarely just a joint issue.

In most cases, it is driven by muscle imbalance and altered neuromuscular control, particularly in individuals with prolonged desk-based postures (Falla, O’Leary and Farina, 2021).

Over-active / tight muscles

Certain muscles tend to become dominant and overactive:

Upper Trapezius

• Elevates the shoulders and assists neck extension

• Increased activity is commonly seen in individuals with neck pain

Levator Scapulae

• Connects the scapula to the upper cervical spine (C1–C4)

• Tightness increases compressive forces on upper cervical joints

Suboccipital Muscles

• Small stabilising muscles at the base of the skull

• Become overactive in forward head posture

• Associated with upper cervical compression and headaches

Sternocleidomastoid (SCM)

• Becomes more active in forward head posture

• Alters normal movement patterns and cervical alignment

These changes in muscle activity have been consistently linked to altered cervical mechanics and increased load on passive structures (Palomeque-del-Cerro et al., 2020; Falla, O’Leary and Farina, 2021).

Under-active / weak muscles

At the same time, key stabilising muscles often become inhibited:

Deep Cervical Flexors (Longus Colli & Longus Capitis)

• Provide segmental stability to the cervical spine

• Help control movement and reduce strain on joints

Dysfunction in these muscles is commonly observed in individuals with neck pain and is associated with reduced stability and increased mechanical stress on cervical joints (Jull and Falla, 2019).

How this leads to pain

When this imbalance develops:

• Tight muscles increase joint compression

• Weak muscles reduce joint support

This creates a cycle of:

Muscle imbalance → joint overload → irritation → protective muscle tension

Over time, this can contribute to facet joint irritation, reduced movement quality, and persistent pain.

What you might feel

This combination of joint and muscle dysfunction can present in several ways:

• Localised neck pain (often one-sided)

• Pain with extension or rotation

• Stiffness, particularly after desk work

• Reduced range of motion

• Headaches

• Referred pain into the shoulders or upper back

(Stemper and Yoganandan, 2019).

What about “trapped nerves”?

Many people describe their symptoms as a “trapped nerve”.

While true nerve irritation (cervical radiculopathy) can occur, research shows that many cases of neck pain are mechanical in nature, rather than neurological (Thoomes et al., 2018). This means symptoms may feel similar — including referred pain — but are often driven by joint and muscle dysfunction, rather than direct nerve compression.

Understanding referred pain

Both muscles and facet joints can refer pain to other areas.

For example:

• Facet joints → neck, shoulder, and upper back

• Upper trapezius & levator scapulae → neck and shoulder

• Suboccipitals → head (headaches)

This overlap is one of the reasons neck pain can feel widespread and difficult to pinpoint.

Conclusion

Neck pain is rarely caused by just one structure.

It is usually the result of postural loading, muscle imbalance, and joint irritation

Understanding how these interact is key. It’s not just about tight muscles, and it’s not just about the joint —it’s about how your body is being loaded every day.
