Lower Back Pain: Causes, Symptoms, Treatments, Exercises & Prevention Tips

Do you suffer from lower back pain or lumbago? You’re not alone. Lower back pain is a common issue that can affect anyone, regardless of age, lifestyle, or past injuries. It often develops without warning and isn’t always linked to a specific cause or risk factor. In many cases, the pain isn’t serious and may improve on its own with time and self-care. However, sometimes it’s your body’s way of signaling that something needs attention.

Key Facts about Lower Back Pain

• In 2020, about 619 million people worldwide suffered from lower back pain (LBP). By 2050, this number is expected to rise to 843 million, mainly due to population growth and aging.
• Low back pain is the leading cause of disability globally, and it’s the condition where the most people can benefit from proper treatment and rehabilitation.
• Anyone can experience lower back pain at any age, and most people will face it at least once in their lifetime.
• Low back pain is especially common in people over 45 years old, with the highest rates between ages 50 and 55. Women are generally more affected than men.
• New research shows that up to 25% of chronic lower back pain cases may be caused by infections in the spinal discs. A new antibiotic called PP353 has shown encouraging results, with 60% of patients reporting significant pain relief.
• A study from the University of Oxford found that teenagers with severe menstrual cramps are more likely to develop chronic pain, including lower back pain, as adults. This highlights how early pain experiences may impact long-term sensitivity to pain.

What is Lower Back Pain?

Lower back pain, or lumbago, is a common condition that affects the muscles, bones, and nerves in the lower back. It is the area between the bottom of the ribs and the top of the buttocks. It can occur at any age and impacts millions of people in the U.S. and around the world. The pain can feel like a dull, constant ache or a sudden sharp sensation, making it hard to move or perform daily tasks.

Low back pain is usually classified by how long it lasts:

• Acute pain lasts less than 6 weeks,
• Sub-chronic pain lasts between 6 to 12 weeks, and
• Chronic pain lasts more than 12 weeks.

It can also be grouped by its cause:

• Mechanical pain results from muscle strain or spine issues,
• Non-mechanical pain is related to infections, inflammation, or other health problems, and
• Referred pain is felt in the back but originates from another part of the body.

Additionally, low back pain can be:

• Non-specific – when no definite cause can be found; this accounts for about 90% of all cases
• Specific – when there is a clear cause like an injury, structural problem, or disease

Low back pain can affect more than just physical health. It may interfere with work, reduce participation in social activities, and lead to stress, anxiety, or depression.

People living with this condition often struggle with mobility and find it harder to stay active or engage with family and friends.

Rehabilitation is essential for all types and stages of low back pain. It helps individuals understand and manage their pain, stay active, return to activities they enjoy, and develop strategies to support recovery and improve function.

In some cases, specialized care pathways may be needed to address specific causes and provide targeted treatment.

Lower Back Pain Symptoms

Lower back pain can manifest in various ways and affect individuals differently. Some of the most common signs and symptoms include:

• Sudden or gradual pain: The discomfort may start quickly after an activity or develop slowly over time. Sometimes you may hear or feel a “pop” when the pain begins.
• Pain without a clear cause: In many cases, there isn’t an obvious reason for the pain.
• Type of pain: It can feel sharp, stabbing, dull, or achy. The intensity may fluctuate or remain constant.
• Radiating pain (sciatica): Pain may travel down your buttocks, hips, or legs, especially if a nerve is irritated.
• Pain that changes with movement: Bending, lifting, or sitting for long periods may make it worse, while lying down or changing positions may bring relief.

Other Symptoms You May Notice

• Stiffness: You may find it hard to straighten your back or move comfortably. Standing up from a chair or bed can feel slow and painful, and you might need to walk or stretch to loosen up.
• Posture changes: Lower back pain can make it difficult to stand tall. You may lean to one side, look slightly crooked, or lose the natural curve in your lower spine.
• Muscle spasms: After an injury or strain, the muscles in your lower back may tighten or contract suddenly. These spasms can cause severe pain and may limit your ability to stand, walk, or move.

When to See a Doctor

Mild lower back pain often improves with rest, stretching, or over-the-counter pain relief. However, you should contact a healthcare provider if:

• The pain is severe or does not improve after a few weeks.
• It keeps you from doing normal daily activities.
• You experience numbness, tingling, or weakness in your legs.
• The pain is accompanied by fever, sudden weight loss, or loss of bladder/bowel control.

What are the Causes of Lower Back Pain

Lower back pain is one of the most frequent health problems worldwide. Your lumbar spine (the bones in your lower back) plays a major role in almost every movement you make. These vertebrae:

• Support most of your body weight.
• Provide stability for the entire spine.
• It acts as an attachment point for muscles and ligaments that help you sit, walk, run, lift, and twist.
• Work is the center of your body’s balance.

Because the lower back has so many important functions, even small issues with its bones, muscles, discs, or joints can cause significant pain.

Most common causes of lower back pain:

1. Muscle Strains and Ligament Sprains – Strains and sprains are the leading cause of lower back pain. They often happen when lifting heavy objects, bending awkwardly, or twisting suddenly. Even sneezing or coughing can sometimes trigger a strain. Symptoms usually include stiffness, soreness, and difficulty moving comfortably.
2. Spinal Fractures – Accidents, falls, or injuries can cause fractures in the lumbar spine. Conditions like osteoporosis (weak bones) make these fractures more likely, especially in older adults. A stress fracture called spondylolysis is common in young athletes who put repetitive pressure on the spine.
3. Disc Problems – Spinal discs act like shock absorbers between vertebrae. With age or injury, they can:
   • Bulge or slip (herniated disc), pressing on nearby nerves.
   • Degenerate and lose cushioning (degenerative disc disease).
4. Structural Issues in the Spine – Certain spinal conditions can change the way your back is aligned and lead to chronic pain:
   • Spinal stenosis: narrowing of the spinal canal that puts pressure on nerves.
   • Spondylolisthesis: when one vertebra slips forward over another.
   • Scoliosis: sideways curvature of the spine that may cause stiffness and discomfort.
5. Arthritis in the Spine – Arthritis is another major source of lower back pain. The most common type is osteoarthritis, which leads to joint stiffness and reduced flexibility. Ankylosing spondylitis, an inflammatory arthritis, can cause stiffness, swelling, and pain that worsens over time.
6. Diseases and Other Health Conditions – Sometimes, lower back pain is a symptom of an underlying health issue, such as:
   • Spinal tumors or infections.
   • Kidney stones or urinary tract infections.
   • Abdominal aortic aneurysm.
   • Chronic pain conditions like fibromyalgia.

How to Diagnose Lower Back Pain

Doctors use several methods to find the exact cause of lower back pain. The process usually starts with a detailed discussion about your symptoms, lifestyle, and medical history. A physical examination follows, where your doctor may check your posture, range of motion, muscle strength, and reflexes.

Medical History and Physical Examination

After reviewing your symptoms and medical history, your doctor will perform a physical exam to better understand your back issues. The exam may include:

1. Visual inspection and touch: The doctor will look at your back and gently press on different areas to check for pain, swelling, or tenderness.
2. Movement tests: You’ll be asked to bend forward, backward, and side to side. This helps the doctor see if your range of motion is limited or if certain movements cause discomfort.
3. Nerve function checks: The doctor will test your reflexes at the knees and ankles, as well as your muscle strength and sensation in your legs. These tests help determine if nerve irritation or damage is contributing to your pain.

This thorough evaluation helps your doctor pinpoint the cause of your back pain and recommend the most effective treatment options.

Imaging Tests

If your doctor needs more information to determine the cause of your back pain, several imaging and diagnostic tests may be recommended:

1. X-rays – X-rays are often the first test used to check for obvious problems in the spine. They can reveal broken bones, bone wear from aging, abnormal curvatures, or spinal deformities. However, X-rays do not show soft tissues like muscles, nerves, or spinal discs.
2. Magnetic Resonance Imaging (MRI) – MRI scans provide detailed images of soft tissues, including muscles, nerves, and spinal discs, along with bones and joints. This makes MRIs especially useful for detecting conditions such as herniated discs, spinal infections, or nerve compression.
3. Computed Tomography (CT) Scans – CT scans are like advanced, 3D X-rays that give a detailed view of the bones. If your doctor suspects a bone-related issue, such as a fracture or structural abnormality, a CT scan can help identify it more clearly than standard X-rays.
4. Bone Scan – A bone scan may be recommended if your doctor wants to rule out rare causes of back pain, such as cancer, infection, or hidden fractures. This test helps detect areas of abnormal bone activity and can be crucial for diagnosis.
5. Bone Density Test – If osteoporosis is suspected, a bone density test may be ordered. Osteoporosis weakens bones, making them more prone to fractures. While osteoporosis itself usually doesn’t cause pain, fractures in the spine due to weakened bones can lead to significant back pain.

Why These Tests Matter

Getting the right test can help your doctor pinpoint the cause of your back pain, guide treatment, and prevent complications. Early diagnosis often leads to better outcomes and faster recovery.

Treatment Options for Lower Back Pain

Most cases of mild to moderate lower back pain improve on their own with simple home care. Resting for a short time, applying ice or heat packs, and using over-the-counter (OTC) pain relievers like ibuprofen or acetaminophen often provide quick relief.

After a few days, it’s important to get back to light movement and normal activities—staying active helps increase blood flow, reduces stiffness, and speeds up recovery.

However, if your pain is severe, persistent, or caused by an accident (such as a fall or sports injury), you should seek medical care right away.

Common Treatments for Lower Back Pain

The best treatment depends on the cause, severity, and duration of your pain. Your doctor may recommend one or more of the following options:

1. Medications
   • Nonsteroidal anti-inflammatory drugs (NSAIDs) or stronger prescription pain relievers can help manage inflammation and discomfort.
   • In some cases, muscle relaxants may be prescribed to ease painful spasms.
2. Physical Therapy (PT)
   • A physical therapist can design exercises to strengthen your core and back muscles, improve flexibility, and support spinal health.
   • PT also focuses on posture correction and proper body mechanics to prevent future injuries.
3. Manual or Hands-On Therapy
   • Treatments such as chiropractic adjustments, osteopathic manipulation, or massage therapy can help reduce tension, restore mobility, and improve spinal alignment.
4. Injections
   • For chronic or severe pain, doctors may suggest lumbar epidural steroid injections to reduce inflammation around irritated nerves.
5. Surgery
   • While most back problems don’t require surgery, certain conditions like herniated discs, spinal stenosis, or severe injuries may need surgical repair.
   • Minimally invasive procedures are now available, offering shorter recovery times compared to traditional surgery.

Recovery and Long-Term Management

Healing from lower back pain can take time, especially if it’s a chronic condition. Working closely with your healthcare provider will help you find the most effective treatment plan.

In addition to medical care, adopting healthy habits—such as regular stretching, low-impact exercise, weight management, and proper ergonomics—can prevent flare-ups and keep your back strong in the long run.
