Sacroiliac Joint Injections
What Are Sacroiliac Joint Injections?
A sacroiliac joint injections (SI) are injections of local anesthetic and a steroid medication into the sacroiliac joint. Due to the numbing medicine used during this procedure, you may experience temporary pain relief afterwards that may last several hours. Once the numbing medicine wears off, however, your pain will most likely return. The steroid medication may give longer lasting pain relief and usually begins working after 24-48 hours.
Risks related to this procedure tend to be relatively minor and occur infrequently. Typical risks include:
- Risks related to the medications used in the injection, such as a possible allergic reaction to a medication.
- Bruising and/or soreness at the injection site.
- Infection at the injection site, deeper tissues, or in the joint.
