Back and neck pain are extremely common, but sometimes the problem involves more than sore muscles or temporary stiffness. A herniated disc can irritate or compress a nearby nerve, potentially causing pain that travels into an arm or leg along with numbness, tingling, or weakness.
The good news is that having a herniated disc does not automatically mean you need spine surgery. Many people improve with conservative treatment. The important question is determining what is causing your symptoms and whether there are signs that warrant evaluation by a spine specialist.
A herniated disc occurs when material from one of the discs between the vertebrae pushes through or beyond its normal boundary and may irritate a nearby nerve. Herniated discs can occur in the cervical spine (neck) or lumbar spine (lower back). Symptoms can include neck or back pain, radiating arm or leg pain, numbness, tingling, and muscle weakness. Persistent symptoms, significant weakness, or other neurological changes should be evaluated by a medical professional.
At Plano Orthopedic & Sports Medicine Center, our comprehensive approach to spine care includes evaluation, nonsurgical treatment options, physical therapy, and surgical treatment when appropriate.
What Is a Herniated Disc?
Your spine is made up of individual bones called vertebrae.
Between many of these vertebrae are discs that act as cushions and help the spine move. Each disc has a softer inner portion surrounded by a tougher outer layer.
When disc material pushes through or beyond the outer portion of the disc, it can potentially irritate or compress a nearby spinal nerve.
Where the herniation occurs helps determine the symptoms you may experience.
A herniated disc in the cervical spine can affect the neck, shoulders, arms, and hands.
A herniated disc in the lumbar spine can affect the lower back, buttocks, legs, and feet.
What Causes a Herniated Disc?
Disc herniation can happen for several reasons.
Sometimes there’s a specific event, such as lifting something heavy or twisting awkwardly. In other cases, changes develop gradually as the discs undergo normal age-related wear.
Contributing factors can include:
- Age-related disc degeneration
- Repetitive lifting or bending
- Heavy physical work
- Sudden twisting movements
- Sports injuries
- Traumatic injuries
- Genetics and individual anatomy
- Activities that repeatedly stress the spine
Sometimes patients can’t identify a single moment when the problem started.
They may simply notice increasing back or neck discomfort followed by symptoms extending into an arm or leg.
What Does a Herniated Disc Feel Like?
Not every herniated disc causes symptoms.
Some disc abnormalities are discovered on imaging performed for an unrelated reason.
When a disc does irritate a nerve, however, symptoms may occur along the path of that nerve.
The location of the symptoms can provide important clues about which portion of the spine may be involved.
What Are the Symptoms of a Herniated Disc in the Lower Back?
A lumbar herniated disc may cause lower back pain, but the most noticeable symptom for some patients is actually leg pain.
When a lumbar nerve root becomes irritated or compressed, symptoms may include:
Lower back pain. Pain may remain localized or occur along with symptoms farther down the leg.
Sciatica. Pain may travel from the lower back or buttock into the thigh, calf, or foot.
Numbness or tingling. Patients may notice altered sensation in portions of the leg or foot.
Weakness. Depending on the nerve involved, certain muscles may become weaker.
Pain may sometimes become worse with particular movements, sitting, bending, coughing, or sneezing.
Is Sciatica the Same Thing as a Herniated Disc?
No.
Sciatica describes symptoms caused by irritation or compression involving the sciatic nerve or the nerve roots that contribute to it.
A herniated lumbar disc is one possible cause of sciatica, but it isn’t the only one.
That’s an important distinction because treating “sciatica” effectively means understanding what’s causing the nerve irritation.
What Are the Symptoms of a Herniated Disc in the Neck?
A cervical herniated disc can produce symptoms that extend well beyond the neck.
Patients may experience neck pain accompanied by pain traveling into the shoulder, arm, or hand.
Other symptoms can include tingling, numbness, or weakness.
This type of nerve-related pain is often referred to as cervical radiculopathy.
Depending on which nerve is affected, symptoms may occur in different areas of the arm or hand.
When Is Arm or Leg Numbness a Reason to See a Spine Specialist?
Occasional tingling from sitting or sleeping in an awkward position is different from persistent neurological symptoms associated with neck or back pain.
Evaluation becomes more important when numbness or tingling:
Persists or worsens, repeatedly travels into an arm or leg, occurs along with weakness, interferes with normal activities, or is associated with significant neck or back pain.
Progressive muscle weakness deserves particular attention because it may indicate more significant nerve involvement.
How Is a Herniated Disc Diagnosed?
Diagnosis generally begins with a medical history and physical examination.
The physician may ask where the pain started, where it travels, which activities make it worse, and whether you’re experiencing numbness, tingling, or weakness.
The examination may evaluate:
- Strength
- Sensation
- Reflexes
- Range of motion
- Walking
- Areas of tenderness
- Signs of nerve irritation
When appropriate, imaging such as an MRI may be used to examine the discs, nerves, and other structures of the spine.
The goal isn’t simply to find an abnormality on an image.
The physician needs to determine whether the imaging findings correspond with the patient’s symptoms and examination.
Does a Herniated Disc Always Require Surgery?
No.
Many herniated discs can initially be treated without surgery.
The appropriate treatment depends on the severity of symptoms, neurological findings, duration of the problem, overall health, and how much the condition interferes with everyday activities.
Conservative treatment may include activity modification, medications when appropriate, physical therapy, and other nonsurgical approaches.
The objective is to reduce symptoms while helping the patient safely regain movement and function.
How Can Physical Therapy Help a Herniated Disc?
Physical therapy can be an important part of nonsurgical treatment for some patients with a herniated disc.
Treatment is individualized, but therapy may focus on improving mobility, strengthening muscles that support the spine, addressing movement patterns, and gradually returning the patient to normal activities.
Physical therapy isn’t simply about stretching the painful area.
The therapist considers how the patient moves and which movements or activities increase or decrease symptoms.
We’ve created a companion article explaining this in more detail:
How Can Physical Therapy Help With a Herniated Disc and Sciatica?
When Might Spine Surgery Be Considered?
Surgery may be considered when symptoms don’t improve adequately with appropriate nonsurgical treatment or when the condition is causing significant neurological problems.
Factors a spine surgeon may consider include persistent nerve pain, progressive weakness, significant functional limitations, imaging findings, and how the condition is affecting the patient’s quality of life.
The specific procedure depends on the location and nature of the spinal problem.
For some herniated discs, a procedure such as a microdiscectomy may be considered to remove disc material that’s compressing a nerve.
Other conditions may require different approaches.
The goal isn’t to perform surgery simply because an MRI shows a herniated disc. Treatment should be based on the individual patient’s symptoms, examination, imaging, and response to nonsurgical care.
What Is Motion Preservation in Spine Care?
Modern spine treatment isn’t limited to a choice between living with pain and spinal fusion.
In appropriately selected patients, motion-preservation approaches may be considered.
One example is artificial disc replacement, which may be an option for certain cervical spine conditions. Unlike a fusion, which joins vertebrae together, disc replacement is designed to preserve motion at the treated spinal level.
Not everyone is a candidate.
The appropriate treatment depends on factors such as the patient’s diagnosis, anatomy, symptoms, spinal stability, overall health, and previous treatment.
A spine surgeon can explain whether motion-preserving treatment is relevant to a particular condition.
When Should You See a Spine Specialist?
Consider seeking an evaluation when neck or back pain isn’t improving, repeatedly returns, or begins interfering with normal activities.
An evaluation is particularly important when pain is accompanied by:
- Persistent arm or leg pain
- Numbness or tingling
- Muscle weakness
- Difficulty walking
- Loss of coordination
- Increasing neurological symptoms
Certain symptoms can require more urgent evaluation.
Seek prompt medical attention for severe or rapidly progressing weakness, major difficulty walking, loss of bowel or bladder control, numbness in the saddle/groin area, or symptoms following significant trauma.
Frequently Asked Questions About Herniated Discs
Can a herniated disc heal without surgery?
Many people with disc herniations improve without surgery. Treatment depends on the patient’s symptoms, neurological findings, and individual condition.
What’s the difference between a bulging disc and a herniated disc?
The terms describe different changes in a spinal disc. A bulging disc generally involves a broader extension of the disc, while a herniation involves more focal displacement of disc material. The significance depends on whether the disc is affecting nearby nerves and whether it corresponds with the patient’s symptoms.
Can a herniated disc cause sciatica?
Yes. A lumbar disc herniation can irritate or compress a nerve root and cause pain, tingling, numbness, or weakness extending into the leg.
Can a herniated disc in the neck cause hand numbness?
Yes. Cervical nerve compression can cause symptoms extending into the shoulder, arm, hand, or fingers, depending on which nerve is affected.
Will an MRI tell me if I need spine surgery?
Not by itself. Imaging is one part of the evaluation. Treatment decisions also consider symptoms, physical examination findings, neurological changes, response to conservative care, and the patient’s overall circumstances.
Should I see a spine specialist for persistent sciatica?
Persistent or worsening sciatica—particularly when accompanied by numbness or weakness—may warrant evaluation to determine what’s causing the nerve irritation and which treatment options are appropriate.
