No one should have to live with SI joint pain
SI joint pain is a type of low back pain that can make everyday living difficult. But education and understanding can help get to the bottom of the pain, so you can return to the life you love.
The first key to understanding SI joint pain is understanding the anatomy. SI stands for Sacro-Iliac. There are two Sacroiliac (SI) joints in your body, located on either side of the triangle-shaped bone at the bottom of your spine where it connects to your pelvis. The SI joints are a shock absorber for your spine and provide stability for your body as you run, walk, or jump. Interestingly enough, the SI joints usually don’t move more than 2 – 4 millimeters themselves. But each one contains many nerve endings that can cause significant pain if the joint is damaged or loses its ability to move properly. Everyday wear and tear, arthritis, or a single injury can damage these joints, changing their normal movement and creating chronic and sometimes debilitating SI joint pain that often, generally feels like low back pain.
Chronic SI joint pain is defined as pain originating from a problem with one or both of the SI joints which has lasted for three months or longer. But the connection between low back pain and the symptoms associated with a condition called Sacroiliac (SI) Joint Dysfunction are not always obvious to the people suffering from them, or to treating physicians. When it comes to chronic low back pain, the cause is a problem with an SI joint in about 20% of cases.1 That number rises to 30% in low back pain patients with a previous lumbar fusion.2 If you’re among them, learning about SI joint pain causes, symptoms, diagnosis and treatment options can help you find the relief you need.
