Symptoms of sciatica include low back pain, pain in the buttocks, sometimes shooting pain in the posterior leg or calf, and numbness or tingling in the posterior leg or calf. Sciatica can be caused by different issues, such as a biomechanical dysfunction of the pelvis, direct trauma (including a fall or a sports injury), prolonged sitting, tightening of the piriformis muscle, a compressed nerve root, or a sudden increase in activity. If you are diagnosed with any of these issues, our doctors will work with you to improve movement and reduce pain.
