2016 — More editing, more! Added some better information about pain being a poor indicator, and the role of myofascial trigger points. This article has become extremely busy in the last couple months — about 4,000 readers per day, as described here — so I am really polishing it and making sure that it’s the best possible answer to people’s fears about back pain.
Work on strengthening all of your core muscles and glutes. These muscles work together to give you balance and stability and to help you move through the activities involved in daily living, as well as exercise and sports. When one set of these muscles is weak or tight, it can cause injury or pain in another, so make sure you pay equal attention to all of them.
• Juvenile Spondylarthropathy. Also called juvenile-onset spondyloarthritis (spinal arthritis), this term is used to describe spondylarthropathies that begin before age 16. In addition to affecting the spine, they may cause pain and inflammation in the joints of the pelvis, hips, ankles and knees. They may also affect other body organs such as the eyes, skin and bowels.
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.
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.
