Your SI joints connect the pelvic bones to your spine. They absorb much of the forces of the upper body before transferring weight to the hips and legs. When these joints become irritated or begin to break down, they can cause chronic pain. An SI Joint Injection allows your doctor to confirm that irritation or damage to the SI joint is the source of your symptoms. Your doctor will inject a local anesthetic into the affected SI joint. If this anesthetic relieves your pain, your diagnosis has been confirmed.
Typically, this procedure takes 10-20 minutes, including any preparation time. You can expect to experience immediate albeit temporary relief from the local anesthetic used. The relief from the injection itself will typically begin two to four days post injection and last for several months. SI injections are quite effective in reducing inflammation and providing considerable pain relief for extended periods of time.
