Neurological Causes of Lower Back Pain in Men
This article is for educational and informational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment.
Lower back pain is common, and in many cases it stems from muscles, ligaments, joints, or other mechanical issues. But pain that travels from the lower back into the buttock or leg, or comes with numbness, tingling, or weakness, can point to nerve involvement.
Understanding the causes of lower back pain in men starts with recognizing that the location of the pain does not always indicate where the problem originates. A compressed or irritated nerve in the spine can create symptoms along its entire pathway. Knowing the difference can help you determine when routine care may be appropriate and when a neurological evaluation deserves consideration.
How Common Is Lower Back Pain in Men?
About 28% of men aged 18 and older reported lower back pain during the previous three months, according to CDC (Centers for Disease Control and Prevention) data from the 2018 National Health Interview Survey. Among men, the percentage increased with age up to 74, then declined among adults 75 and older.
Lower back pain can result from something as straightforward as a muscle strain, but it can also involve discs, joints, nerves, or other structures around the spine. Understanding the pattern of your symptoms can help identify when nerve involvement may be part of the problem.
What Causes Lower Back Pain in Men?
There are many causes of lower back pain in men, ranging from muscle and ligament injuries to age-related spinal changes and conditions affecting nearby nerves. Some pain can also be referred from organs such as the kidneys or prostate.
The following are some of the more common causes and patterns worth understanding.
Muscle and Ligament Strain
Muscle strains and ligament sprains are among the most common causes of lower back pain. They can occur after lifting, sudden twisting, overuse, an awkward movement, or poor form during exercise.
This type of pain often stays relatively localized to the lower back. You may notice soreness, stiffness, tightness, or pain when moving in certain directions.
Many uncomplicated strains improve with time and appropriate activity modification. Gentle movement is generally preferable to prolonged bed rest, while activities that significantly aggravate the pain may need to be temporarily reduced.
A muscle strain typically does not cause pain that shoots down the leg or neurological symptoms such as persistent numbness or tingling. When those symptoms appear, another cause may need to be considered.
Herniated or Bulging Disc
The discs between the vertebrae act as cushions and help the spine move. With a herniated disc, material from inside the disc pushes through a weakened area of its outer layer.
A herniated disc does not always cause symptoms. But if the disc material irritates or compresses a nearby nerve, the pain can extend beyond the lower back.
You may experience:
- Pain traveling into the buttock or leg
- Numbness or tingling
- Burning or electric-like sensations
- Muscle weakness
- Pain that changes with certain movements
This is where lower back pain can become a neurological problem rather than simply a muscular one.
Spinal Stenosis and Degenerative Disc Disease
As the spine ages, the discs and joints can gradually change. Degenerative disc disease refers to changes in the discs, while spinal stenosis refers to narrowing of the spaces within the spine.
These changes do not automatically cause pain. The problem arises when degenerative changes narrow the space around a nerve, creating compression.
Lumbar spinal stenosis can cause lower back pain as well as pain, numbness, or weakness in the legs. Some people notice symptoms mainly while standing or walking and experience relief when sitting or leaning forward.
Age-related changes become more common as people get older, but having an abnormal finding on imaging does not necessarily mean it is the source of your pain. Your symptoms and physical examination are important when determining whether a spinal change is clinically significant.
Sciatica and Nerve Compression
Sciatica describes pain that follows the pathway of the sciatic nerve, usually extending from the lower back or buttock down the back or side of the leg. It may sometimes continue toward the foot.
Sciatica commonly occurs when a nerve root in the lower spine is irritated or compressed, often because of a herniated disc or spinal stenosis.
Unlike typical muscle soreness, nerve-related symptoms may include:
- Sharp or shooting pain
- Burning sensations
- Tingling
- Numbness
- Weakness in the leg or foot
The severity and location depend on which nerve is affected.
If you are experiencing persistent numbness or tingling along with back or leg pain, a neurological evaluation can help determine whether the symptoms are related to nerve dysfunction.
Organ-Referred Pain: Kidney or Prostate Problems
Not every type of lower back pain comes from the spine.
Pain from an organ near the lower back can sometimes be perceived in the back even though the underlying problem originates elsewhere. This is called referred pain.
Kidney problems, including kidney stones or infection, can cause pain in the back or side. Depending on the condition, symptoms may also include fever, painful urination, blood in the urine, nausea, or pain that does not change significantly with movement.
For men, certain prostate conditions can also cause pain or discomfort in the lower back or pelvis, particularly when accompanied by urinary symptoms.
These symptoms do not diagnose a kidney or prostate condition by themselves. They are simply important details to mention to your doctor because they may point toward a cause outside the nervous system.
How to Tell If Your Lower Back Pain Is a Nerve Problem
Nerve-related lower back pain often radiates into the buttock or leg and may cause numbness, tingling, burning, or weakness. Muscle or ligament pain is more often localized and feels like an ache, soreness, or tightness.
That distinction is useful, but it is not enough to diagnose a nerve condition on your own.
During a neurological evaluation, a neurologist may assess:
- Muscle strength
- Reflexes
- Sensation
- Coordination
- Walking and balance
- The distribution of pain or altered sensation
These findings can help determine whether symptoms correspond to a particular nerve or nerve root.

Red Flag Symptoms: When Lower Back Pain Needs Immediate Care
Most cases of lower back pain do not indicate an emergency. Certain symptoms, however, can signal serious nerve compression or another condition that requires prompt medical attention.
Go to the emergency department immediately if lower back pain occurs with:
- New loss of bladder or bowel control
- Difficulty starting or stopping urination
- Numbness around the groin, genitals, inner thighs, or buttocks
- Rapidly worsening weakness in one or both legs
- Severe difficulty walking
These symptoms can occur with cauda equina syndrome, a serious condition involving compression of the bundle of nerve roots at the bottom of the spinal canal.
Other warning signs that warrant prompt medical evaluation include:
- Fever with significant back pain
- Unexplained weight loss
- Pain that steadily worsens despite appropriate care
- Pain that repeatedly wakes you at night
- New or progressive neurological symptoms
The distinction is important: bladder or bowel changes, saddle-area numbness, and rapidly progressing leg weakness require emergency assessment. Persistent back pain, radiating pain, numbness, or tingling without these emergency symptoms generally calls for a timely medical evaluation.
When to See a Neurologist for Lower Back Pain in Huntsville
You may benefit from a neurological evaluation if your lower back pain lasts for several weeks, keeps returning, or is accompanied by symptoms that suggest nerve involvement.
Consider scheduling an evaluation if you have:
- Pain that travels into the buttock or leg
- Persistent numbness or tingling
- Burning or electric-like pain
- Leg or foot weakness
- Difficulty walking or maintaining balance
- Symptoms that are worsening rather than improving
- Back pain that continues despite conservative care
The Neurology Institute of Huntsville evaluates lower back pain by looking for the underlying cause rather than treating every case the same way. Its current approach begins with conservative measures when appropriate, including activity modification, posture and body-mechanics changes, physical therapy, and strengthening.
Depending on the cause and severity, treatment may also include medication, interventional procedures, or surgery.
For patients who need more advanced evaluation, Dr. Jitesh Kar brings board certification, fellowship training, and a particular interest in diagnostic neurology and neuromuscular disorders to the practice.
If you are in Huntsville or the surrounding North Alabama area and your back pain is accompanied by neurological symptoms, schedule an appointment with the Neurology Institute of Huntsville or call 256-489-0976.
How Is Neurological Lower Back Pain Diagnosed?
A diagnosis begins with your symptoms and medical history rather than an imaging scan alone.
Your neurologist may ask:
- When did the pain start?
- Did it begin after an injury or gradually?
- Does the pain travel into your buttock or leg?
- Do you experience numbness, tingling, or burning?
- Have you noticed weakness?
- Does standing, walking, sitting, bending, or coughing change the symptoms?
- Have you experienced bladder or bowel changes?
- Have you had previous back problems or surgery?
A neurological examination can then evaluate strength, reflexes, sensation, coordination, gait, and other functions.
Depending on the findings, your clinician may recommend additional testing. MRI can provide detailed images of discs, the spinal canal, and structures surrounding the nerves. EMG/NCS may be useful when there is a question about nerve or muscle function.
What Treatment Is Available for Neurological Lower Back Pain?
The right lower back pain treatment depends on what is causing the symptoms, how severe they are, how long they have lasted, and whether there is neurological impairment.
Conservative Treatment
Many cases can initially be managed without surgery. Depending on the diagnosis, treatment may include:
- Maintaining appropriate physical activity
- Physical therapy
- Improving posture and body mechanics
- Exercises that strengthen the core and supporting muscles
- Activity modification
- Medications when appropriate
The goal is generally to reduce symptoms while maintaining function and addressing factors that may be contributing to the problem.
Epidural Injections
For selected patients with radicular pain, an epidural steroid injection may be considered when conservative treatment has not provided sufficient relief.
A 2025 American Academy of Neurology systematic review found that epidural steroid injections may provide modest short-term improvements in pain and disability for some patients with lumbar radicular pain, while evidence for long-term benefit was limited.
That does not mean injections are appropriate for every patient. The underlying diagnosis, symptom severity, examination findings, and potential risks all need to be considered.
Surgery
Surgery may be considered when a structural problem is causing significant nerve compression, particularly when symptoms are severe, progressive, or fail to improve with appropriate nonsurgical treatment.
Procedures may include:
- Microdiscectomy for selected herniated discs
- Laminectomy for certain cases of spinal stenosis
- Spinal fusion for selected structural problems
Is Lower Back Pain in Men Always a Neurological Problem?
No. This is one of the most important distinctions to understand.
Most lower back pain is related to the musculoskeletal system rather than a neurological disorder. A strain after lifting something heavy, for example, may produce localized soreness without affecting the nerves.
Neurological involvement becomes more likely when back pain is accompanied by symptoms such as:
- Pain radiating into the leg
- Numbness
- Tingling
- Burning or electric-like sensations
- Muscle weakness
- Changes in walking or balance
There can also be overlap. A person may have a mechanical back problem and nerve irritation simultaneously.
Final Thoughts
There are many lower back pain causes in men, and most are not neurological. Muscle strain, ligament injury, degenerative changes, and other mechanical problems are common. However, a herniated disc, spinal stenosis, or another condition can compress or irritate a nerve and cause a very different pattern of symptoms.
Pay particular attention if lower back pain radiates into the leg or is accompanied by numbness, tingling, burning, weakness, or changes in walking. These symptoms can indicate nerve involvement and may warrant a neurological evaluation.
FAQs
Q1. What causes lower back pain in men?
Lower back pain in men can result from muscle or ligament strain, herniated discs, spinal stenosis, degenerative disc changes, or nerve compression. Pain can also sometimes be referred from organs such as the kidneys or prostate. The symptoms and pattern of pain help determine which causes to consider.
Q2. Is lower back pain a sign of kidney problems?
It can be. Kidney problems may cause back or side pain, particularly when accompanied by symptoms such as fever, painful urination, nausea, or blood in the urine. Pain from the kidneys may not change significantly with movement or position. These symptoms warrant medical evaluation rather than self-diagnosis.
Q3. What organs can cause lower back pain?
The kidneys can cause pain that is felt in the back or side, while prostate problems can sometimes cause lower back or pelvic discomfort in men. This is called referred pain, meaning the source is an internal organ but the discomfort is perceived elsewhere.
Q4. When is lower back pain serious?
Lower back pain needs urgent attention when it occurs with new bladder or bowel problems, numbness around the groin or buttocks, or rapidly worsening weakness in the legs. Fever, unexplained weight loss, steadily worsening pain, and progressive neurological symptoms also warrant prompt medical evaluation.
Q5. Can a pinched nerve cause lower back pain?
Yes. A compressed nerve root can cause pain in the lower back as well as pain that travels into the buttock or leg. A herniated disc and spinal stenosis are common causes of nerve compression. Numbness, tingling, burning sensations, or weakness can accompany the pain.
Q6. When should I see a neurologist for lower back pain?
Consider seeing a neurologist when back pain persists for several weeks, repeatedly returns, travels into a leg, or causes numbness, tingling, weakness, or changes in walking or balance. A neurological evaluation can help determine whether a nerve is involved and identify an appropriate treatment approach.
