Lower back pain isn’t a mystery in most cases. It follows patterns, and once you understand those patterns, you can do something about them. Up to 80% of people will experience low back pain at some point in their lives, and the causes of lower back pain tend to cluster into three main categories: muscle and soft tissue injuries, disc problems, and structural or chronic conditions. Knowing which one you’re dealing with changes everything about how you recover.
At RxWellness Spine & Health, we see all three on a daily basis. Whether you’ve got a sore lower back from overdoing it at the gym, or you’ve been dealing with deep, persistent pain for months, there’s almost always a specific cause we can identify and treat.
What Muscle and Soft Tissue Problems Cause Lower Back Pain?
Muscle and soft tissue injuries are the most frequent causes of lower back pain. They include back strain, lower back muscle strain, lower back sprain, muscle strain in the back, and back spasm. These injuries typically come on after heavy lifting, a sudden, awkward movement, or extended time in a poor postural position. They’re painful but often very treatable.
Back Strain vs. Lower Back Sprain
People use these terms interchangeably, but they’re not the same thing. Back strain involves damage to muscles or tendons, while lower back sprain involves the ligaments that connect bone to bone. Both can cause a sore lower back, swelling, and reduced range of motion. A lower back sprain tends to feel deeper and more achy, while muscle strain in the back often comes with tightness and spasms.

What Triggers a Back Spasm?
A back spasm is your nervous system’s emergency response. When a back muscle is overstretched or under sudden load, the surrounding muscles contract to protect the injured area. Back pain is a leading cause of morbidity and disability in the United States, and back spasms are one of the most common reasons people end up in our clinics for the first time. If you’ve had a back spasm, you know how alarming it can feel. The good news is that lower back muscle strain and spasms respond well to targeted chiropractic care and soft tissue therapy.
Risk Factors You Can Control
- Lifting with your back instead of your legs
- Sitting for long hours without postural support
- Weak core muscles that force the low back to compensate
- Sudden increases in exercise intensity without proper buildup
Our back pain treatment breaks down how we approach soft tissue injuries and what treatment looks like at each stage of recovery.
If your back strain isn’t getting better after a few days of rest, that’s your sign that something more is going on. Our team can pinpoint the exact cause and build a treatment plan that works.

How Does a Slipped Disk in the Back Cause Lower Back Pain?
A slipped disk in the back, also called a herniated or bulging disc, is one of the most significant structural causes of lower back pain. It happens when the soft, gel-like center of a spinal disc pushes through a weakened outer wall and presses on nearby spinal nerves. The result is often intense, localized pain that may radiate down one or both legs.
What Does It Mean to Have Slipped a Disk?
When someone says they’ve slipped a disk, they usually mean that one of the discs between their lumbar vertebrae has herniated. This can happen gradually from years of wear, or it can result from a sudden injury like heavy lifting or a fall.
The level at which the disc herniates determines where the pain travels. A disc problem at L4-L5 or L5-S1, the most common levels, typically sends pain into the buttocks, thighs, and calves.
Symptoms That Set Disc Problems Apart From Muscle Injuries
Knowing the difference between a disc issue and a back muscle problem matters because the treatment approach differs.
Signs you may have a slipped disk in your back rather than a muscle injury:
- Sharp or burning pain that shoots down one leg
- Numbness or tingling in the foot or calf
- Pain that worsens when sitting or bending forward
- Muscle weakness in the leg or foot
- Pain that doesn’t improve with a few days of rest
Can Chiropractic Care Help With Disc Problems?
Yes, in most cases. Spinal manipulation, flexion-distraction therapy, and targeted decompression techniques can reduce pressure on an affected disc and relieve nerve irritation. Our multidisciplinary approach to spine care combines chiropractic adjustments with physical therapy and, when appropriate, regenerative medicine to support disc healing without surgery.

What Structural and Chronic Conditions Are Causes of Lower Back Pain?
Beyond acute injuries and disc problems, structural and chronic conditions are significant causes of lower back pain that are often underdiagnosed. These include arthritis, spinal stenosis, scoliosis, and degenerative disc disease. In 2019, 39% of U.S. adults reported back pain in the past three months, and a substantial portion of those cases involved underlying structural issues that went beyond a simple strain or sprain.
How Degenerative Disc Disease Contributes to a Sore Lower Back
Degenerative disc disease isn’t actually a disease in the traditional sense. It’s a term that describes the natural breakdown of spinal discs over time. As discs lose hydration and height, they become less effective as shock absorbers. This leads to increased joint stress, back spasms, stiffness, and a persistently sore lower back that tends to flare with activity and ease with rest.
Spinal Stenosis and How It Feels
Spinal stenosis occurs when the spinal canal narrows and compresses the spinal cord or nerve roots. It’s a common cause of lower back pain in adults over 50. People with stenosis often feel significant relief when leaning forward, like when pushing a shopping cart, because that position temporarily opens the spinal canal. Pain that worsens with walking or standing and improves with sitting or bending forward is a classic pattern we assess for in our clinics.
Sciatica as a Symptom of a Deeper Cause
Sciatica isn’t a diagnosis by itself. It’s a symptom. When the sciatic nerve is compressed, whether by a herniated disc, bone spur, or spinal stenosis, it sends pain down the back of one leg. Our sciatica treatment explains how we identify the cause of sciatic nerve compression and treat it at its source rather than just quieting the symptom.
Arthritis in the Spine
Osteoarthritis of the lumbar spine causes joint inflammation, bone spur formation, and stiffness that make everyday movement difficult. It’s one of the more chronic causes of lower back pain we treat, and it often coexists with other conditions like stenosis or disc degeneration.
Chronic back pain doesn’t have to be your new normal. Whether it’s a structural issue, a disc, or a persistent muscle problem, our team is built to find it and treat it. Call the nearest RxWellness Spine & Health clinic or request an appointment online to get an evaluation that actually digs into the root cause.
How Do You Know Which Cause of Lower Back Pain You Have?
You can’t know for certain without a proper assessment. Symptoms overlap significantly between muscle injuries, disc problems, and structural conditions. A sore lower back after yard work could be a simple back strain, a lower back sprain, or the beginning of a flare triggered by underlying disc disease. The history of your pain, where it travels, and what makes it better or worse all matter.
What a Thorough Evaluation Looks Like
At RxWellness Spine & Health, an initial evaluation for lower back pain typically includes:
- A detailed health and injury history
- Orthopedic and neurological testing to check reflexes, strength, and sensation
- Postural and range-of-motion assessment
- Imaging referrals when clinically indicated
This isn’t a one-size-fits-all process. The goal is to identify the specific cause of lower back pain for you so we can build a treatment plan around that, not around a generic protocol.
When to Come In Instead of Waiting It Out
Most low back pain from back strain or back spasm starts to improve within a few days. If yours hasn’t improved within a week, or if you have any of the following, you should be evaluated promptly:
- Leg pain, numbness, or weakness alongside your back pain
- Pain that wakes you from sleep
- Back pain following an injury, fall, or accident
- Pain that doesn’t change with position
Our team offers care across multiple locations in Virginia, Maryland, and Washington D.C. so you can get in quickly without a long wait. Our work with patients dealing with the most common causes of lower back pain has been featured on WJLA/ABC7’s Good Morning Washington, which named RxWellness among the area’s premier healthcare experts.
Frequently Asked Questions
What’s the difference between back strain and a lower back sprain?
Back strain involves damage to the muscles or tendons supporting your lumbar spine, while a lower back sprain involves the ligaments that connect the vertebrae. Both can cause a sore lower back with swelling, stiffness, and reduced movement. They often feel similar, which is why a professional evaluation is important. Treating them as the same condition can slow recovery if the wrong tissues are being targeted.
How long does muscle strain in the back usually take to heal?
Mild to moderate lower back muscle strain typically improves within two to six weeks with appropriate care. Rest, ice in the first 48 hours, gentle movement, and hands-on treatment all help the process along. Without addressing the underlying mechanics that caused the strain, though, re-injury is common. That’s why we don’t just treat the pain but look at posture, movement patterns, and muscle balance as well.
Can a slipped disk in the back heal on its own?
In some cases, yes. A herniated disc can partially reabsorb over time as the immune system breaks down displaced disc material. This process can take weeks to months and isn’t guaranteed. During that window, pain management, spinal decompression, and physical therapy can significantly reduce symptoms and prevent further damage. Surgery is typically a last resort when conservative care doesn’t provide sufficient relief.
What does a back spasm feel like compared to general back pain?
A back spasm is a sudden, involuntary tightening of one or more back muscles that can feel like a sharp cramp or a deep, locking sensation. Unlike a general ache from a sore lower back, spasms often make it impossible to move normally for several seconds or minutes. They can be triggered by a specific movement or appear without an obvious reason. Spasms that repeat frequently often signal an underlying structural or disc problem that needs assessment.
Is lower back sprain common after a car accident?
Yes, lower back sprain is one of the more common soft tissue injuries after auto accidents, particularly rear-end collisions. The sudden force can overstretch the lumbar ligaments even at low speeds, and symptoms sometimes take 24 to 72 hours to fully develop. Many people dismiss back pain after an accident as minor, but ligament injuries that aren’t properly treated can become a persistent source of instability and chronic discomfort.
What’s the difference between sciatica and regular lower back pain?
Regular lower back pain stays in the lumbar region, while sciatica involves pain that travels along the sciatic nerve, typically from the low back through the buttock and down one leg. Sciatica is a symptom caused by nerve compression, which can stem from a slipped disk in the back, spinal stenosis, or bone spurs. It’s often accompanied by numbness, tingling, or muscle weakness in the leg. Getting an accurate diagnosis matters because sciatica treatment targets the nerve compression, not just the back muscles.
Can I exercise if I have causes of lower back pain that are still active?
It depends on the specific cause and stage of injury. Gentle movement, like walking or light stretching, is almost always encouraged even during recovery. High-impact activities, heavy lifting, or exercises that reproduce your pain should be avoided until you’ve been properly assessed. Our providers can help you identify which movements are safe and which ones are putting unnecessary stress on the injured tissue, so your recovery stays on track rather than getting set back.
Key Takeaways
- The three primary causes of lower back pain are muscle and soft tissue injuries, disc problems, and structural or chronic conditions.
- Back strain and lower back muscle strain are among the most common causes of lower back pain and often result from sudden movement or overuse.
- A slipped disk in the back happens when the soft inner material of a spinal disc pushes through its outer layer and irritates nearby nerves.
- Back spasms are involuntary contractions of the back muscles that can be a sign of both muscle strain in the back and disc involvement.
- Lower back sprain affects the ligaments while back strain affects the muscles and tendons, and both require proper assessment to treat effectively.
- Causes of lower back pain that go untreated often become chronic, meaning the pain lasts longer than 12 weeks and becomes harder to resolve.
- Chiropractic care, physical therapy, and regenerative medicine can address the causes of lower back pain without relying on surgery or medication.
- Poor posture, sedentary habits, and improper lifting are modifiable risk factors for most causes of lower back pain.
- Getting an accurate diagnosis is the most important first step, and that means working with a provider who can identify the root cause rather than just managing symptoms.
Wrap-Up: Understanding Your Lower Back Is the First Step to Fixing It
The causes of lower back pain fall into three main categories: soft tissue injuries like back strain, lower back muscle strain, and back spasms; disc problems like a slipped disk in the back; and structural conditions like arthritis, stenosis, and degenerative disc disease. Each one has a distinct treatment path, and none of them benefits from guessing.
At RxWellness, we’ve built a multidisciplinary care model around exactly that. Our chiropractic and spine care services are designed to get to the source, not just the surface.
