A sacroiliac (SI) joint injection is a treatment to help patients with pain in the buttocks, lower back and hips. These joints connect the bottom of your spine to your pelvis and provide support for the lower part of your body and your back.
You will lie on your stomach on a table. Then the area to be treated will be cleaned and covered with a special sheet. Before the procedure starts, a doctor will inject you with a local anesthetic. This will numb the skin over the area that will be treated. Then your doctor will inject the numbing medication and the steroid medication in the joint(s). You may feel some pressure when the medications will be injected. The entire procedure should take about 10minutes.
A SI joint injection is generally considered safe. The most common side effect is soreness in the injected area. The soreness will go away once the steroid starts to work.
