What will occur prior to my SI joint treatment?
Before undergoing SI joint injection, your doctor will take your full medical history and will examine you to determine if you have a condition that will respond to this type of treatment. Imaging, such as x-rays, and lab tests will most likely be utilized.

What is the procedure for a sacroiliac joint injection?
The procedure for sacroiliac joint injection is performed in a doctor’s office or hospital on an outpatient basis. The procedure includes the following steps.
The entire procedure takes approximately 30 minutes. After the procedure the patient will remain under observation for about one hour before being allowed to go home. If sedation has been used, they will need to have someone on-hand to ensure their safe return to their home.
How long do the effects of SI joint injections last?
Initially, patients feel relief from pain due to the anesthetic. This temporary effect wears off after a day. It then takes two to three days for the patient to feel the effects of the injection. Often with the first treatment, they will experience relief from pain lasting from a few days to several weeks. Additional treatments will then provide longer periods of relief, which often last several months.
What are the risks and possible side effects associated with the procedure?
Because SI joint injection is a minimally invasive procedure the risks are low and side effects tend to be minimal. At the SI joint injection site, one may experience slight swelling, bruising, and bleeding. Other remote risks include an allergic reaction to the medication and nerve, blood vessel, or bone damage from a needle not properly inserted.
There is also the slight chance that an infection may occur. If the injection site becomes hot to touch, continues to swell, or discharges a sizeable amount of fluid or blood, contact your physician immediately. Also, any sign of fever should be reported.
Some patients may have a reaction to the anesthetic, which can include flushing, chest or abdominal discomfort, nausea and/or the development of a rash.
