Your doctor may order imaging tests, such as an MRI, to get more information about the location and cause of the irritated nerve. An MRI can show the alignment of vertebral disks, ligaments, and muscles. A CT scan using contrast dye can also provide a useful picture of the spinal cord and nerves. Determining the cause of sciatica can help guide the course of treatment. X-rays can help identify bony abnormalities but can't detect nerve problems.
When it comes to your workouts, low-impact aerobic exercises are generally best and least likely to cause issues, says Kelton Vasileff, M.D., an orthopedic surgeon at The Ohio State University Wexner Medical Center. “I recommend swimming, walking, elliptical, cycling, and stationary biking for general exercise,” he says. All of these are great ways to move your body without pounding your joints.
The sacroiliac joint typically has little motion. Small movements at the joint help with shock absorption and forward/backward bending. The joint is reinforced by strong ligaments surrounding it, some of which extend across the joint in the back of the pelvis. This network of soft tissues provides support, limits movement at the joint, and assists with absorbing pressure.
The cross-legged twist will stretch the outside of your hips and part of your buttocks. Sit crossed-legged on the floor and then lift your right leg and place your foot on the outside of the bent left leg. Twist your upper body to look over your right shoulder. You can reach your left arm to the outside of your right leg to hold the stretch and place your right hand on the floor behind you for support. After 30 to 40 seconds, switch sides.
Grade III (severe): A complete tear in your muscle that causes severe pain and swelling and you can't bear weight on that leg, making it difficult to walk. You've also lost more than 50 percent of your muscle function. These injuries are less common and may need surgery to repair the torn muscle. They can take several months or more to completely heal.
