Herniated intervertebral disc – Symptoms, Diagnosis and Treatment

A herniated intervertebral disc, commonly referred to as a herniated disc, is one of the most common causes of spinal pain and pain radiating to a limb.

In the lumbar spine it may cause sciatica, buttock pain, leg numbness, tingling, or muscle weakness.

A herniated intervertebral disc is a common reason for consultation among patients with low back pain, pain radiating to the leg, or neurological symptoms. Proper treatment requires not only an assessment of the MRI report, but above all a clinical examination and correlation of symptoms with MRI or CT findings.

Not every disc herniation requires surgery. In many cases, non-surgical treatment is possible and includes pharmacotherapy, rehabilitation, activity modification, and selected minimally invasive procedures. Surgical treatment is considered in cases of paresis, red-flag symptoms, significant compression of neural structures, or lack of improvement despite appropriate treatment.

What is an intervertebral disc herniation?

An intervertebral disc is located between the vertebral bodies and acts as a shock absorber. It consists of an outer part, the annulus fibrosus, and an inner part called the nucleus pulposus. Degenerative or overload-related changes may result in disc damage and displacement of disc material.

An intervertebral disc herniation occurs when a fragment of the disc moves beyond its normal position. If it irritates or compresses a nerve root, it may cause radiating limb pain, numbness, tingling, or muscle weakness.

Disc herniation most commonly affects the lumbar spine, especially the L4-L5 and L5-S1 levels. However, it may also occur in the cervical spine, where symptoms may radiate into the upper extremity.

Herniated disc, bulging disc and discopathy – what is the difference?

Patients often encounter terms such as discopathy, protrusion, bulging disc, or herniated disc in their test reports. Discopathy is a broader term referring to pathology or damage of the intervertebral disc.

A bulging disc generally refers to disc protrusion without complete disruption of disc structures, whereas a herniation indicates a more advanced displacement of disc material. Clinical significance depends not only on imaging findings but primarily on symptoms and whether neural structures are compressed.

Most common causes of  herniated intervertebral disc

A herniated disc can occur suddenly, for example, after bending over, lifting a heavy object, or making a sudden movement. In many patients, however, it is the result of long-term overuse.

Contributing factors include:

• Prolonged sitting
• Spinal overload
• Improper lifting technique
• Lack of regular physical activity
• Weak core muscles
• Overweight and obesity
• Smoking
• Previous spinal injuries
• Degenerative disc changes

Symptoms of a herniated intervertebral disc

Symptoms depend on the location of the herniation and whether it is compressing a nerve root. In some patients, a herniation visible on an MRI does not cause significant symptoms. In others, it can cause severe pain and neurological symptoms.

The most common symptoms of a lumbar herniated disc are:

• Low back pain
• Pain radiating to the buttock, thigh, calf or foot
• Sciatica
• Lower-limb numbness
• Tingling or electric-shock sensations
• Muscle weakness
• Difficulty walking on toes or heels
• Increased pain during sitting, coughing, sneezing or bending

In the cervical spine, herniation may cause neck pain, pain radiating to the shoulder or arm, finger numbness, tingling, or reduced grip strength.

Herniated intervertebral disc vs. sciatica

Intervertebral disc herniation is one of the most common causes of sciatica. Sciatica occurs when displaced disc material irritates or compresses a nerve root in the lumbosacral spine.

A typical symptom is pain radiating from the lower back through the buttock into the lower limb. Pain may worsen with sitting, bending, coughing, or sneezing. Numbness, tingling, and muscle weakness may also occur.

When should you see a specialist?

Consultation is recommended when spinal pain radiates to a limb, persists despite treatment, recurs, or significantly limits daily functioning. Specialist assessment is particularly important if numbness, tingling, muscle weakness, or gait disturbances occur.

An orthopedist specializing in spinal care can determine whether the symptoms are caused by a herniated disc, discopathy, spinal stenosis, degenerative changes, or another cause.

Red-flag symptoms:

• Progressive limb weakness
• Foot drop
• Bladder or bowel dysfunction
• Perineal numbness
• Loss of sensation in one or both limbs
• Rapidly worsening neurological symptoms
• Severe pain despite treatment
• Pain after major trauma

Diagnosis of herniated intervertebral disc

Diagnosis begins with medical history and physical examination. The physician evaluates pain location, radiation pattern, muscle strength, sensation, reflexes, and signs of nerve root irritation.

The most important imaging study is magnetic resonance imaging (MRI) of the spine. MRI allows assessment of intervertebral discs, disc herniation, the spinal canal, neural foramina, and the degree of neural compression.

Additional tests may include CT, spinal X-ray, dynamic X-ray studies, and neurophysiological tests such as EMG.

Correlation of MRI findings with clinical symptoms is essential. The presence of a herniation on imaging does not automatically mean that surgery is required.

Treatment of herniated intervertebral disc

Treatment depends on the severity of symptoms, the degree of compression of nerve structures, and the presence of neurological symptoms. In many patients, treatment without surgery is possible, especially if there is no progressive weakness or red-flag symptom.

Treatment without surgery

Non-surgical treatment may include analgesic and anti-inflammatory medications, rehabilitation, activity modification, and gradual return to physical activity. Prolonged bed rest is generally not recommended, as it can lead to muscle weakness and delay recovery.

Rehabilitation should be tailored to the individual. The appropriate approach will differ during the acute phase of radicular pain versus chronic pain or after the acute symptoms have subsided.

Minimally invasive pain treatment

For selected patients with radicular pain, minimally invasive pain management procedures, such as epidural injections or selective nerve root blocks, may be considered. The goal is to reduce pain and inflammation around irritated neural structures.

The decision to pursue such treatment requires an examination of the patient and an analysis of MRI or CT images.

When is surgery needed?

Surgical treatment is considered in cases of progressive paresis, foot drop, cauda equina syndrome, significant neural compression, or severe persistent pain despite properly conducted conservative and minimally invasive treatment.

The aim of surgery is to remove the cause of compression and decompress neural structures. The extent of surgery depends on herniation location, patient symptoms, and imaging findings.

The most important step is to determine whether the abnormality seen on imaging actually corresponds to the patient’s symptoms. Combining clinical examination, neurological findings, and MRI analysis allows proper treatment planning.

Treatment options may include conservative management, rehabilitation, minimally invasive spine pain treatment, or qualification for surgery. The aim is pain reduction, functional improvement, and safe return to daily activities.
