Back pain is one of the most common health complaints worldwide, affecting 619 million. In the United States, up to 84% of adults will experience it at some point in their lives. It impacts people of all ages and lifestyles.
Many cases of back pain are mild, short-lived, and are due to muscle strain or poor posture. However, some forms of pain may signal a more serious issue, such as a herniated disc.
Knowing the difference between regular back pain and a herniated disc can help you know when to see a doctor.
What Is a Herniated Disc?
The spine is composed of vertebrae separated by discs that serve as cushions or shock absorbers. These discs are composed of a soft, gel-like center, known as a nucleus, and a tougher outer layer, referred to as an annulus.
A herniated disc occurs when the nucleus pushes out through a tear in the annulus. This can irritate or put pressure on nearby nerves, leading to pain, numbness, tingling, and weakness in the areas served by those nerves.
Herniated discs most commonly occur in the lower back (lumbar) and neck (cervical) regions of the spine. However, they can also occur anywhere along the spine. They are usually caused by age-related wear and tear, injury, repetitive strain, or other factors.
Generalized Back Pain vs. Herniated Disc: How to Tell the Difference
When you are suffering from back pain, how do you know if it is generalized pain versus a herniated disc? Figuring that out usually requires a visit to a medical specialist to obtain an accurate diagnosis. However, here are some indicators to consider:
1. Location and Nature of Pain
General Back Pain: Typically, general back pain is characterized by dullness, aching, or tightness. It tends to be localized as lower back pain and may improve with rest or after taking over-the-counter medications.
Herniated Disc: A disc herniation often presses on nerves at the point where they exit the spine. As a result, the symptoms people first notice are nerve dysfunction or damage.
You may feel pain or tingling in the neck or lower back, which may radiate out to the extremities. When the herniation occurs in the lower back, it may cause a sharp, shooting pain that radiates down one or both legs. This is a condition commonly known as sciatica.
This pain can be worse when sitting, coughing, sneezing, or bending forward. It may also worsen when standing.
2. Numbness, Tingling, or Weakness
General Back Pain: When you only have general back pain, you normally won’t have additional neurological symptoms.
Herniated Disc: When a herniated disc presses against a nearby spinal nerve, you may feel pain along the nerve’s path. This can cause tingling or numbness in one or both legs, feet, or other parts of the body.
You may notice additional symptoms such as:
- Lower back pain.
- Tingling or numbness in the legs and/or feet, or other extremities.
- Muscle weakness.
- Pain while sitting and rising from a sitting position.
- Worsening pain from prolonged standing.
- Pain when bending forward.
- Pain improves throughout the day after rising.
3. Duration and Progression
General Back Pain: General back pain typically improves within a few days to weeks with home care.
Herniated Disc: Cervical and lumbar disc herniations may resolve on their own without treatment. This is because discs can naturally shrink or disappear over time, a process called resorption.
However, significant pain and frequent numbness may persist or worsen over time. This may indicate more serious conditions that could lead to permanent nerve damage if not treated. In these cases, you should see a doctor as soon as possible.
When severe back and leg pain is accompanied by loss of bladder or bladder function, you should seek immediate treatment from a local emergency room.
4. Response to Movement
General Back Pain: General back pain may feel better with gentle movement or stretching.
Herniated Disc: With disc herniation, movement often will make the pain worse. This particularly will occur with activities that increase pressure on the spine.
Lumbar Spinal Stenosis vs. a Herniated Disc
So far, we’ve discussed the distinction between a herniated disc and more general back pain. However, there is another significant condition that can lead to sciatica, characterized by symptoms such as pain, numbness, tingling, or weakness spreading down one or both legs.
The other condition is Lumbar Spinal Stenosis. Lumbar Spinal Stenosis is a degenerative condition frequently found in people over the age of 50.
When bone overgrowth causes lumbar spinal stenosis, it can squeeze the nerve roots. This can irritate, compress, or pinch the nerves, leading to back pain and other nerve-related issues, such as sciatica. Spinal stenosis occurs gradually and is common in older adults.
On the other hand, a herniated disc usually occurs more suddenly. It is normally the result of age-related wear and tear, sudden injuries, or strains.
The sciatica symptoms for lumbar spinal stenosis are like those for a herniated disc. Pain is often in the buttocks, runs down the leg, and may continue into the foot. It may involve one or both legs.
However, other symptoms of lumbar spinal stenosis often involve neurogenic claudication, including:
- Lower back pain.
- A heavy feeling in your legs, which may lead to cramping.
- Numbness or “pins and needles” tingling in the buttocks, legs, or feet.
- Pain worsens when standing for long periods, walking downhill, or bending backward.
- Pain that lessens when you lean forward, walk uphill, or sit.
When Should You See a Doctor?
You should consult a doctor if:
- Your pain lasts more than a few weeks.
- You experience numbness, tingling, or weakness in your legs.
- The pain is severe or getting worse and is not relieved by rest or over-the-counter medications.
- You are unable to perform daily activities due to the pain.
- You have difficulty walking.
- You experience a loss of bladder or bowel control. This symptom suggests a potential medical emergency, possibly indicating cauda equina syndrome. If this occurs, you should seek medical treatment immediately.
Diagnosis and Treatment
A doctor might perform a physical examination and request imaging tests such as an MRI or CT scan to diagnose a herniated disc or lumbar spinal stenosis.
Treatment options vary based on severity:
- Conservative care: Pain relievers, anti-inflammatory drugs, and rest.
- Physical therapy: Physical therapy to strengthen spine-supporting muscles and improve flexibility and balance.
- Injections: Corticosteroid injections in the epidural space around pinched spinal nerves to help reduce inflammation, pain, and irritation.
- Surgery: Surgery is only considered in rare cases where all other treatment options have failed to provide adequate relief.
Takeaway
While most back pain is not a sign of a serious condition, certain symptoms—especially pain radiating into the leg, numbness, or weakness—may point to a herniated disc or lumbar spinal stenosis.
Early evaluation and treatment can help prevent complications and promote a faster recovery. When in doubt, it’s always better to seek medical advice rather than wait for symptoms to worsen.
