A Sacroiliac (SI) Joint Injection is a medical procedure that serves both a diagnostic and therapeutic purpose for individuals experiencing lower back pain related to the sacroiliac (SI) joint. Approximately 25% of people with lower back pain have SI joint involvement. Factors like aging, injury, or misalignment can disrupt the SI joint function and cause pain. If pain immediately improves with the injection, it’s a good indicator that the SI joint is to blame.

Q. How is a Sacroiliac (SI) Joint Injection Performed?
A pain doctor uses imaging technology (such as ultrasound) to guide the placement of the injection. The goal is to deliver the medication directly into the SI joint. Pain reduction can serve as a valuable diagnostic tool after the procedure. If pain improves immediately after receiving an injection, it suggests the SI joint was involved.
Q. What are the benefits and potential risks associated with a Sacroiliac (SI) Joint Injection?
A Sacroiliac (SI) Joint Injection provides temporary pain relief by reducing inflammation and swelling of nerves in the sacroiliac joint. Depending on the type and dosage of medication used, the pain relief can last from several days to months. Possible injection side effects may include mild pain, allergic reaction, muscle weakness and in rare cases, nerve injury.
Q. What is the recovery time following this type of injection?
Following the procedure, patients are routinely monitored for any adverse effects. Pain relief usually occurs within minutes to hours. Your provider will recommend a follow-up appointment to assess the effectiveness of the injection and address any concerns.
