What is a lumbar strain?
A lumbar strain is an injury to the lower back, which results in damaged tendons and muscles that spasm and feel sore. The lumbar vertebra make up the section of the spine in your lower back.
What causes lumbar strain?
Injury can damage the tendons and muscles in the lower back. Pushing and pulling sports, such as weight lifting or football, can lead to a lumbar strain. In addition, sports that require sudden twisting of the lower back, such as in tennis, basketball, baseball, and golf, can lead to this injury. Certain risk factors, such as excessive lower back curvature, forward-tilted pelvis, weak back, or abdominal muscles, and tight hamstrings, can increase the risk for this injury.
What are the symptoms of lumbar strain?
The following are the most common symptoms of a lumbar strain. However, each person may experience symptoms differently. Symptoms may include:
- Sudden lower back pain
- Spasms in the lower back that result in more severe pain
- Lower back feels sore to the touch
The symptoms of a lumbar strain may resemble other conditions and medical problems. Always consult your doctor for a diagnosis.
How is lumbar strain diagnosed?
In addition to a complete medical history and physical exam, diagnostic procedures for low back pain may include the following. However, during many initial assessments and exams, specialized tests aren't recommended.
- X-ray. A diagnostic test that produces images of internal tissues, bones, and organs onto film.
- Computed tomography scan (also called a CT or CAT scan). A diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of bones, muscles, fat, and organs.
- Magnetic resonance imaging (MRI). A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.
- Radionuclide bone scan. A nuclear imaging technique that uses a very small amount of radioactive material, which is injected into the bloodstream to be detected by a scanner. This test shows blood flow to the bone and cell activity within the bone.
- Electromyogram (EMG). A test to evaluate nerve and muscle function.
How is lumbar strain treated?
Specific treatment for a lumbar strain will be determined by your doctor based on:
- Your age, overall health, and medical history
- Extent of the injury
- Your tolerance for specific medications, procedures, and therapies
- Expectation for the course of the injury
- Your opinion or preference
Treatment may include:
- Ice packs and compression applied to the back
- Exercises (to strengthen the abdominal muscles)
- Stretching and strengthening exercises (for the lower back as it heals)
- Education regarding the use and wearing of appropriate protective equipment
Medications, such as anti-inflammatories and spinal injections may also be used to relieve pain and inflammation.
When should I call my health care provider?
Call your health care provider if any of the following occur:
- You’re unable to stand or walk.
- You have a temperature over 101.0°F (38.3°C)
- You have frequent, painful, or bloody urination.

Contact your health care provider immediately for the following:
- Pain radiating down the leg
- Pain that is accompanied by fever, weakness in the leg, or loss of control of the bladder or bowels
Living with lumbar strain
Cold reduces swelling. Both cold and heat can reduce pain. Protect your skin by placing a towel between your body and the ice or heat source.
- For the first few days, apply an ice pack for 15 to 20 minutes .
- After the first few days, try heat for 15 minutes at a time to ease pain. Never sleep on a heating pad.
- Over-the-counter medications can help control pain and swelling. Try aspirin or ibuprofen.
Exercise can help your back heal. It also helps your back get stronger and more flexible, preventing any reinjury. Ask your doctor about specific exercises for your back.
Use good posture to avoid reinjury
- When moving, bend at the hips and knees. Don’t bend at the waist or twist around.
- When lifting, keep the object close to your body. Don’t try to lift more than you can handle.
- When sitting, keep your lower back supported. Use a rolled-up towel as needed.
- Lumbar refers to your lower back.
- Strain can cause damage to the tendons and muscles causing pain and soreness.
- Non-surgical methods can cure most low back pain.
- Call your health care provider if symptoms don’t get better over the next several days or if symptoms get worse.
