You may begin to notice an improvement in your pain 2-5 days after the injection. If you do not notice improvement within 10 days after the injection, it is unlikely to occur. You may take your regular medications after the procedure, but try to limit them for the first 4-6 hours after the procedure, so that the diagnostic information obtained from the procedure is accurate. You may be referred for physical or manual therapy after the injection while the numbing medicine is effective and/or over the next several weeks while the cortisone is working.
“So when we do the SI Joint injection, we typically want to start off by getting a true lateral image, which looks like this. This is where the anterior and posterior SI joints are superimposed, okay, which is what we see in this particular picture. Then what I’m going to do is I’m going to rotate it towards me, and what you’re going to notice here is that the SI Joint is going to start to separate. And that’s what we’re seeing right now, to the point that we basically see our posterior joint, which is right here, and our anterior joint, which is right here, separating completely. Okay. And what we think is that the posterior joint, which is the medial one, is located right here: this is our opening. So this is basically where we’re going to want to make our mark, and anesthetize the skin.”
Many people begin to notice meaningful pain relief within two to five days after an injection. If the treatment proves to be beneficial, its effects may last for one week up to one year. If necessary (and at the discretion of a physician), a patient can typically receive up to three injections during a one-year period. Any more than that, however, can increase the risk of side effects, such as osteoporosis (weakened bone tissue). That’s because cortisone can inhibit the body’s production of vitamin D, which in turn can interfere with the absorption of calcium that’s essential for strong bones.
