Treatment typically focuses on strengthening and stabilizing the muscles of the back and legs and improving posture to reduce strain on the joints and relieve nerve pressure.

Because imaging such as X-rays or MRI often shows similar findings in people with and without pain, these conditions should not be diagnosed on imaging alone. A thorough physical examination, including neurologic testing, functional tests, and postural assessment, is essential to determine whether these findings are truly the source of your symptoms.

It can be caused by many issues, including any of the spinal conditions described elsewhere, or by central sensitization—a state in which the nervous system becomes overly sensitive after an initial injury and continues to interpret normal signals as painful and dangerous, even when the original tissue has healed.

Treatment focuses first on identifying the true underlying cause. When central sensitization is involved, care often includes gradual, guided exposure to movement, load, and activity to help retrain the nervous system and reduce its heightened pain response. Because conditions like central sensitization and non-specific low back pain may not show clear changes on imaging, it is critical that your healthcare team compares imaging and test results with your specific pain patterns and symptoms to make an accurate diagnosis.

A physical therapist, physician, or chiropractor can usually identify sciatica with tests like the slump test or straight leg raise, and then perform further assessment to determine which structure is causing the problem.

In many cases, sciatica is related to muscular tightness or restrictions around the hips, and can be improved with targeted exercise and hands-on manual therapy. Although sciatica can be quite uncomfortable, it is not usually due to severe or sudden damage. However, new or sudden weakness, numbness, or loss of sensation along the nerve’s distribution is a warning sign and should be evaluated promptly by a neurologist or other qualified medical provider.

Not all cases are painful, but when the translation is significant, it can narrow the central canal where the spinal cord travels and compress nearby nerves. Common symptoms include numbness, tingling, or loss of muscular control along the affected nerve pathways; these signs typically warrant evaluation and possible referral to a neurologist.

When there are no significant neurological symptoms and the condition is stable, treatment often focuses on postural retraining and strengthening the muscles that support the spine to reduce strain and improve stability. However, in rare but serious cases, spondylolisthesis can affect the nerves that control bowel and bladder function. If you experience sudden changes in bowel or bladder control, or new numbness in the saddle or pelvic region, you should contact your physician immediately for emergency assessment.

In some cases, a disc may bulge or herniate (when the inner nucleus pushes through the outer layer) toward the spinal cord or nerve roots, sometimes causing sciatic-type symptoms. The commonly used term “slipped disc” is a non-medical phrase typically referring to these bulging or herniated disc conditions.

The encouraging news is that most bulging and herniated discs (about 60–90%) improve over time without surgery. Because the initial injury can cause local muscle guarding and irritation, treatment often includes a combination of specific exercises and manual therapy to calm the area and restore normal movement. Imaging such as MRI is no longer considered sufficient on its own to diagnose disc-related pain; a careful physical examination, including neurological testing and correlation with your symptoms, is essential to determine whether the disc is truly the source of your pain.

This type of strain can range from mild irritation of small facet joints to larger muscle strains in the back, such as the erector spinae or quadratus lumborum.

Treatment focuses on gradually restoring both motion and strength while respecting your body’s current limits. You and your therapist will work together to move and load the area within your symptom tolerance, using exercises to promote healing and improve function without provoking a flare-up. Hands-on techniques and other modalities may be used to help calm the nervous system and reduce protective muscle guarding. Importantly, newer research shows that the intensity of pain does not always match the amount of tissue damage—imaging like MRI may be normal even when pain is severe. This does not mean your pain “isn’t real”; it simply reflects how strongly the nervous system is reacting, and it often means surgery is not needed.
