Cause of Neck Pain
Neck pain may be due to soft tissues (muscles, ligaments) or the cervical spine (nerves, disc or facet joints and bone). The most common causes of neck pain are soft tissue abnormalities due to injury or prolonged wear and tear. Occasionally, infection or tumors may cause neck pain. In some people, neck problems may be the source of pain in the upper back, shoulders or arms.
Many things can trigger neck pain. These include direct injury, stress, awkward position of neck (repetitive strain), ergonomic strain.
There are several theories about why so many people suffer neck pain, but they are not supported by scientific proof. Hence it has spawned an entire industry of neck pillows, supports, collars and other aids. For some people, no specific reason for the neck pain can be found.
Road traffic accidents involving whiplash injury may result in acute or chronic neck pain that takes several months to improve.
People under too much stress work their 'anti-gravity muscles' too hard suffer from neck pain and tension headaches.
Common causes of neck pain:
- Slipped disc/Disc prolapsed (see condition)
- Nerve impingement/compression (see condition)
- Facet Joint syndrome (see condition)
- Muscle and Ligamental pain syndrome - Fibromyalgia (see condition)
Non-specific neck pain
Many people develop a stiff and painful neck for no obvious reason. It may happen after sitting in a draught (cold wind of aircon) or after a minor twisting injury, for example while gardening. The underlying cause for this type of neck pain is not fully understood, so it is called 'non-specific neck pain'. Having non-specific neck pain does not mean that your neck is damaged and often it happens in people whose necks would appear completely normal under an x-ray. It is the most common type of neck pain and often disappears after a few days.
'Whiplash'
This type of injury often follows a rear-end collision in a car. In this type of collision, first the body is carried forward and the head flips backwards. Then, as the body stops, the head is thrown forwards (see Figure 3). Following a whiplash injury there is often a delay before the pain and stiffness start. Most common injuries are to the soft tissues, i.e., muscles and ligaments. Severe injury with fracture or dislocation of the neck may damage the spinal cord and cause paralysis (quadriplegia).
Although whiplash can badly damage your neck, the majority of people who suffer these shunt accidents do not have major damage. In most cases injuries feel better within a few weeks or months. Seat belts and properly adjusted headrests in cars have significantly reduced the damage from whiplash injuries.
Tension
Most muscles of the body relax completely when they are not being used but some muscles (known as 'anti-gravity muscles') have to work all the time in order to keep your body upright. Muscles at the back of your neck must always be tensed, otherwise your head would fall forwards when you are sitting or standing. When these muscles work too hard it can cause neck pain and tension headaches. People who are worried or under stress often tighten their muscles more than is necessary to hold their head upright - in other words, they are literally 'tense'. Tension headaches are very common and are often wrongly called migraines.
Rine Neck
Patients wake up in the morning with a stiff neck and progressively become a painful neck when turning the head. The natural history is that the neck pain may recover in 1 week. However, this pain can be extremely distressing and uncomfortable. Rine neck is due to tensed neck muscles during sleep, especially disturbed sleep. Along with poor blood circulation and cold environment, the tensed muscles will go into spasm and become a trigger knot.
Diagnosing Neck Pain
Determining the source of the pain is essential to recommend the right method of treatment and rehabilitation.
Your pain specialist will take a complete history of the difficulties you are having with your neck. He or she may ask you about other illnesses, any injury that occurred to your neck and any complaints you have associated with neck pain. Previous treatment for your neck condition will also be noted. Next a physical examination may include evaluation of neck motion, neck tenderness, and the function of the nerves and muscles in your arms and legs.
Radiological studies often will be done to allow your doctor to look closely at the structures in your neck. These diagnostic techniques often help pain specialists to determine the cause of neck pain and to prescribe effective treatment.
Patients who require further evaluation may undergo one or more of the following examinations:
- MRI (magnetic resonance imaging). This imaging study allows an evaluation of the spinal cord and nerve roots.
- CT (computed tomography). This specialized X-ray study allows careful evaluation of the bone and spinal canal.
- Myelogram (injection of a dye or contrast material into the spinal canal). This specific X-ray study also allows careful evaluation of the spinal canal and nerve roots.
- EMG (nerve conduction and electromyogram). This test evaluates nerve and muscle function.
How neck pain is treated depends on what the diagnosis reveals. However, patients can be treated successfully with rest, medication, immobilization, physical therapy, exercise, activity modifications, and non-surgical methods which include minimally invasive pain procedures.
Your pain specialist is a medical doctor with extensive training in the diagnosis and non-surgical treatment of the musculoskeletal system, including bones, joints, ligaments, tendons, muscles and nerves.
