What does cervical disc herniation mean and why does it occur?

The term hernia refers to a condition caused by the displacement of an organ from its natural cavity. A herniated disc is defined as a neurological condition and occurs when a disc of the spine shifts. Intervertebral discs are cartilages located between the vertebral bodies. These discs have three important roles:

• they allow the mobility of the vertebrae;
• they ensure the stability of the spine;
• they protect the vertebrae from shocks or wear, acting like a shock absorber.

The intervertebral disc is made up of two components: the fibrous ring and the nucleus pulposus. The hernia appears when the fibrous ring ruptures and the nucleus pulposus moves through that fissure. In most cases, the nerve is compressed by the nucleus, which causes the pain specific to herniation [1].

Cervical spondylosis is a disease characterized by degeneration of the intervertebral disc of the cervical spine, and the symptoms can be classified into three groups:

• local signs (pain, stiffness, etc.);
• cervical disc herniation;
• cervical myelopathy (a spinal cord condition).

Cervical disc herniation occurs when the gelatinous material inside an intervertebral disc shifts and presses on the nerve roots or spinal cord. This situation leads to irritation, inflammation, and, in many cases, persistent pain or numbness radiating toward one or both arms.

Main causes of cervical disc herniation:

• prolonged sitting at the desk in an incorrect position;
• prolonged computer use without movement breaks;
• lifting weights without proper technique;
• repeated microtraumas in athletes or people with intense physical activity;
• age-related changes that affect the structure of the discs.

A common example: an active person who suddenly changes the position of the head while lifting weights can develop a cervical herniation within a few weeks. Such “accidents” do not occur only in athletes, but also in those who rushed at work or transported heavy packages.

Adults aged between 25 and 55, including those who do not practice sports regularly, frequently face symptoms of this kind. You can find complete information about mechanisms and other recommendations on the Centrokinetic blog.

What signs should make you consult a doctor?

Neck pain appears occasionally in many people, but when it becomes persistent and radiates, it should not be ignored. Cervical herniation can compress the nerves, leading to cervical radiculopathy, with symptoms that affect the arms.

Initially, the pain may be moderate, but it progresses. Ignoring the signs can worsen the situation, leading to muscle weakness or more serious neurological problems. Consult a doctor if the symptoms persist for more than a few weeks or interfere with daily activities [2].

Warning signs that require a prompt consultation:

• pain in the neck or back of the neck that persists or intensifies with movement;
• tingling or numbness along the arm, shoulder, or in the fingers;
• weakness in the hand or difficulty grasping objects;
• stiffness or limitation of head movements.

These manifestations can vary from mild to major limitations. The precise diagnosis is made only after clinical examination, completed by imaging investigations (MRI or CT). Self-evaluation can lead to delays and complications, which is why it is recommended to schedule a consultation if you recognize yourself in the examples above. Details about modern diagnostic methods can be found at Centrokinetic, within the medical recovery, orthopedics, and neurology services.

Treatment options for cervical disc herniation

Most cervical herniations (over 80-90%) improve without surgery, through conservative methods. The goal is to reduce inflammation, decompress the nerve, and restore functionality [2].

Conservative options (the first recommended)

• redirecting activities that strain the cervical area and temporary rest;
• physical therapy based on an adapted program, for muscle relaxation and posture correction;
• integrated physiotherapy: the use of currents, heat, electrotherapy, or ultrasound;
• anti-inflammatory or analgesic medication (only under the supervision of a doctor);
• local infiltrations in selected cases.

Minimally invasive techniques – low-level laser therapy

Based on numerous reports in the specialized literature regarding the effectiveness of low-level laser therapy for different types of musculoskeletal pain and through our previous experiences using this therapy also for pain in other areas, we considered that low-level laser therapy (LLLT) could be an appropriate treatment for pain associated with cervical disc herniation. We also believed that the spinal cord manifestations associated with cervical myelopathy, including spasticity, can be reduced with this therapy (LLLT).

However, in this study [3], only a few cases of cervical myelopathy were observed; therefore, the results related to cervical myelopathy were excluded.

Pain caused by cervical disc herniation tends to be localized in the neck and shoulder joints, but referred pain in the back region is also observed when the cervical disc herniation is extensive. The purpose of this study was to investigate the effectiveness of low-level laser therapy as a treatment method for cervical disc herniation.

Surgery – reserved for cases with severe symptoms and lack of response

Surgery (discectomy, fusion, or disc replacement) is considered if the symptoms persist for more than 6-12 weeks, progressive weakness or myelopathy appears. It is effective, but involves risks and a longer recovery [2].

The treatment plan is refined depending on your diagnosis and functional goals, for the fastest and safest possible recovery.

Laser therapy in cervical herniation: what does it involve and when is it indicated?

The medical laser directs energy in a controlled way toward the affected area, stimulating healing, reducing inflammation, and relieving pain. In the case of cervical herniation, laser therapy involves localized application, with the purpose of:

• quickly calming the pain, whether chronic or acute;
• reducing the inflammation that presses on the nerves;
• accelerating the tissue repair process;
• restoring mobility in the neck joints.

This intervention does not require incisions or hospitalization and, used correctly, does not cause significant negative effects.

Recommendations for using the laser

Laser therapy is applied in the following scenarios:

• imaging confirmation of a cervical disc herniation or protrusion with persistent symptoms;
• absence of complications such as paralysis or profound neurological deficits;
• the desire to avoid classic surgery, when you have obtained limited benefits from conventional therapy;
• the recovery stage after surgery, upon the express recommendation of the specialist doctor.

Possible contraindications: pregnancy (for the treated area), local oncological diseases, active infections, epilepsy. Each situation is analyzed individually.

Case study

This study included 15 men and 11 women between 36 and 76 years old (average age of 55.5 years). All subjects had a confirmed diagnosis of cervical disc herniation (chronic type). The diagnosis of the disease was based on X-rays, MRI, and physical symptoms [3].

How pain and range of motion are evaluated

Pain was evaluated after treatment using a visual analogue scale (VAS). Also, after treatment, cervical spine flexion and extension were measured to evaluate changes in range values.

The scores at the initial level and at the final evaluation are presented above. The mean VAS scores before treatment were 65.4 13.8 and after treatment were 38.1 8.8. The mean decrease was 26.92 13.2 points. A significant improvement was observed. Regarding range of motion, no significant changes were observed in the absence of pain [3].

Lifestyle guidance

Patients were recommended to follow their normal lifestyle. We provide written advice sheets regarding maintaining good posture, to avoid sitting on a chair or when sitting at a table or desk, to perform daily rotation, flexion, and extension exercises of the head and neck. Patients were advised to avoid postures that induce pain and we strived to guide patients on how to avoid incorrect positions in their day-to-day activities. In discussions with the patients, it was reported, in all cases, that the lifestyle guide provided by us was understood and the advice was followed.

How laser therapy sessions for cervical herniation are carried out

The stages of the consultation and treatment procedure

• The specialist analyzes the MRI or CT results and determines the exact area where the laser is applied.
• You prepare the cervical area and adopt a relaxed position (usually sitting or lying down).
• The doctor uses approved devices – such as MLS laser, HILT, diode – and sets the parameters individually.

How a session actually takes place

• duration: usually, 10–20 minutes;
• the specialist places the treatment handpiece on the affected areas according to a precise scheme;
• the movements can be circular or longitudinal, adapted to the condition.

Each patient follows a protocol of 6–12 sessions, depending on evolution and medical recommendations.

The effects of low-level laser therapy

The frequency at which cervical spondylosis is observed in affected patients is quite high. The prognosis is good for patients with neck pain and cervical disc herniation. However, it is believed that the prognosis for cases involving signs of the spinal cord (cervical myelopathy) is generally poor, and such patients were not evaluated in the present study due to the low number. On the other hand, the present study confirms the beneficial effects of low-level laser therapy.

Pain-reduction countermeasures are important because the pain experienced by patients reduces efficiency at work and/or is an obstacle in daily activities.

The main treatment protocols prescribed for patients with cervical disc herniation in orthopedic departments are relaxation treatments, together with medication and cervical traction. Due to age-related changes, disc herniation is induced more frequently in middle-aged and elderly people. The treatment is simple and easy to administer without side effects. The level of patient satisfaction is also very high. The positive effects of low-level laser therapy. The authors believe that reduction of muscle tone, improvement of blood flow, increase of the pain threshold, and regulation of the nervous system are the main factors.

How the multidisciplinary medical team contributes to your recovery

Optimal recovery involves collaboration between orthopedic doctors, neurologists, physiokinetotherapists, and physiotherapists. These specialists guide you as follows:

• they establish a diagnosis based on modern investigations and your complete history;
• they configure the individual recovery plan: laser therapy, physical therapy, physiotherapy, or medication;
• they monitor the response and make adjustments at each stage;
• they educate the patient to modify the habits that favored the condition.

At Centrokinetic, collaboration between departments ensures interdisciplinary evaluations, functional testing, and progress tracking with the help of internationally validated protocols.

Why timely evaluation and rapid intervention matter

If you go to the doctor when the symptoms have appeared, the chances of returning to your activities without resorting to invasive interventions increase. Prompt and correct evaluation helps you benefit from:

• detecting possible complications at the right time;
• quickly choosing the appropriate therapy;
• reducing the risk of worsening or of involving other cervical segments;
• increased efficiency of preventive measures.

Individual evaluation and attention to every detail make the difference in preventing relapses and reducing long-term discomfort.

Prevention: simple measures for protecting the cervical area

Routine changes can help, in the long term, maintain the health of the cervical spine. Adopt the following recommendations:

• keep the correct alignment of the neck at the office or in the car;
• take breaks every 30 minutes for relaxation and light stretching;
• lift heavy objects with the proper technique and avoid unnecessary strain on the neck;
• use a pillow with medium support, neither very high nor very low;
• if you practice sports – ask a coach to supervise your execution technique.

You can find practical resources and prevention guides on the Centrokinetic website.

Laser therapy or surgical intervention? How do you decide what suits you?

The decision is made after a detailed evaluation of the symptoms, analysis of investigation results, and discussion with the specialist. Laser therapy does not replace the need for surgery when severe neurological problems occur (for example, marked weakness or loss of reflexes).

Benefits of laser therapy:

• it does not require incisions or hospitalization;
• the risk of complications remains low;
• it allows resuming daily activity in a short time;
• it can be associated with other conservative methods.

Limits of laser therapy:

• effectiveness decreases in very large herniations or with rapidly installed paralysis;
• it requires your involvement in physical therapy and changing daily habits;
• the individual response differs and sometimes the protocol must be adapted.

Collaborate with the medical team to make the right decision for your situation.

The patient journey: from diagnosis to recovery with the help of laser therapy

Many patients notice:

• decreased pain and tension after 3–4 sessions;
• improved mobility and more restful sleep;
• gradual return to sports or professional activity.

For example, a 40-year-old IT employee, with neck pain and numbness in the right arm, returned to training after 7 sessions, followed by specialized physical therapy. Each case differs, however, and progress depends on the speed of intervention and compliance with recommendations. If you have similar symptoms, schedule a medical evaluation at Centrokinetic!

Proper evaluation and personalized plan: what benefits does it bring you?

Each patient needs an individual analysis and a treatment plan adapted to their symptoms and goals. An updated evaluation, carried out by the multidisciplinary team, brings:

• precision in diagnosing the cervical condition;
• exclusion of other causes (ligament injuries, rheumatic diseases, bone conditions);
• establishing an appropriate treatment protocol;
• detailed monitoring and adjustments at each stage of recovery.

The personalized approach increases the chances of rapid recovery, with minimal risk of relapse or subsequent restrictions. The active involvement of the medical team represents the main advantage of a successful program.
