Symptoms of Sciatica vs. SI Joint Dysfunction

Persistent lower back discomfort could be caused by either sciatica or sacroiliac (SI) joint dysfunction, both of which present similar symptoms that require diagnostic tests to differentiate. SI joint dysfunction occurs when the joint between the spine and pelvis malfunctions, resulting in sciatica-like lower back and leg pain. In contrast, sciatica arises from the compression, irritation, or inflammation of the lower back nerve, which radiates pain along the sciatic nerve - the longest nerve in the body that runs from the lower back through the hips, buttocks, and down each leg. These conditions usually manifest on one side of the body and vary in severity.

Understanding the underlying causes of sciatica and SI joint dysfunction is critical to distinguishing between the two conditions.

Sciatica can result from:

⛔️ Herniated disc

⛔️ Bone spur

⛔️ Spinal canal constriction

SI joint dysfunction can be triggered by factors such as arthritis or pregnancy.  This knowledge can help you assess your symptoms and provide a basis for discussion with your healthcare provider.

If you suspect that you are experiencing sciatica or SI joint dysfunction, it is advisable to seek professional help. While self-care measures, such as rest, hot/cold packs, and gentle stretching, can alleviate sciatic nerve pain for some people, excessive inactivity could worsen your symptoms.

Medical treatment options include:

✅ Medications

✅ Physical Therapy

✅ Corticosteroid Injections

✅ Acupuncture

✅ Chiropractic Adjustments

depending on the severity of your condition and your physician's recommendations.
