What is a lumbar strain or sprain?
A strain involves the muscles and the tendons that anchor them. A sprain involves the ligaments that hold the vertebrae together. Both cause pain and stiffness in the lower back, often after a specific lift, twist, or fall.
What separates a simple strain from something more serious is the presence of nerve symptoms. Pain that stays local usually points to soft tissue. Pain that shoots down a leg with numbness or weakness points toward the disc or a nerve, which changes the plan.
Lumbar strain and sprain symptoms
- Aching or spasm in the lower back, often after a specific movement
- Stiffness and reduced range of motion
- Pain that worsens with bending, lifting, or prolonged sitting
- Tenderness across the muscles beside the spine
When to seek care right away
Get urgent help for any of these
- Pain that radiates down a leg with numbness or weakness, which points beyond a simple strain
- Pain after a significant fall or accident
- Back pain with fever, or pain that is worse at night with unexplained weight loss
- Numbness in the groin area or any change in bowel or bladder control. Go to the emergency room.

What causes a lumbar strain
Lifting something too heavy or lifting with poor mechanics, a sudden twist, a slip or fall, or repeated overuse are the usual triggers.
Lumbar strain is the classic on-the-job back injury. It shows up after a heavy lift, an awkward carry, a slip on a wet floor, or a shift of repeated bending. Because it is so common at work, it is also the injury where a clear return-to-work plan matters most.
How Dr. Merola diagnoses lumbar strains and sprains
Dr. Merola examines you and, when the story or the exam raises a flag, reads imaging himself to rule out a herniated disc, fracture, or nerve involvement. Confirming that the injury is only a strain is what lets you rehabilitate with confidence.
Every patient meets with Dr. Merola directly. He reads your imaging himself.
Lumbar strain and sprain treatment: conservative care first
Non-surgical care first
- Most strains resolve with a short period of relative rest, gradual return to movement, and guided physical therapy. Prolonged bed rest slows recovery and is avoided.
- Anti-inflammatory care and heat or ice for symptom control.
- A progressive strengthening plan so the same injury is less likely to recur.
When surgery is indicated
- A true lumbar strain does not require surgery. Surgery only enters the conversation if evaluation reveals a different problem, such as a herniated disc or fracture, driving the pain.
Recovering from a lumbar strain: what to expect
Recovery from a lumbar strain varies with the extent of the injury, prior back health, job demands, and response to gradual movement and rehabilitation. Prolonged bed rest is generally avoided unless a clinician gives different instructions.
Modified-duty and full-duty decisions are individualized. Appropriate restrictions depend on pain, mobility, strength, progress, and the specific work tasks.
If this happened on the job
Lumbar strain is the single most reported back injury on the job: a heavy lift, an awkward carry, a slip on a wet floor, a shift of repeated bending. It is also the injury most likely to be dismissed until it stops improving.
Dr. Merola is an authorized New York Workers' Compensation Board provider (authorization 189354-4).
Work status and activity restrictions are based on the examination, imaging, diagnosis, treatment plan, and the demands of the individual job. Tell the office that the condition may be work-related when scheduling so the visit can address those clinical questions.
The New York Workers' Compensation Board publishes official guidance for injured workers at wcb.ny.gov. Questions about filing deadlines, benefits, coverage, or a claim's status should be directed to the Board or a qualified legal professional.

Frequently Asked Questions
What should I do if I hurt my back at work?
Seek evaluation, avoid activities that clearly worsen symptoms, and consult the New York Workers' Compensation Board for official reporting and claim guidance. Urgent neurologic symptoms require immediate medical care.
How long does a lumbar strain take to heal?
There is no universal timeline. Recovery depends on the extent of the injury, prior back health, activity demands, and response to treatment. Pain that travels down a leg or comes with weakness deserves a closer look.
Do I need an MRI for a lower-back strain?
Not always. Imaging is ordered when the exam or history suggests something beyond a strain, such as nerve symptoms or a possible fracture. Dr. Merola reads those studies himself.
When is a lower-back injury more than a strain?
When pain radiates into a leg with numbness or weakness, when it follows a significant fall, or when it does not begin to settle. Those signs point toward a disc, nerve, or fracture.
Where can I find reporting guidance for a back strain at work?
The New York Workers' Compensation Board publishes official information for injured workers at wcb.ny.gov. A medical evaluation can address the diagnosis, treatment, and activity restrictions.
What can modified duty look like for a back strain?
Restrictions may address lifting, repetitive bending or twisting, and position changes through the shift. Appropriate limits depend on the examination, progress, and actual job demands.
