Sacroiliac Joint Injection Side Effects and Risks

Following the injection, the patient usually remains for 30 minutes to ensure that there are no immediate complications or adverse reactions, such as allergic reaction or leg weakness / numbness. The doctor or other team member will determine when it is safe for the patient to go home.

Following a diagnostic or combination diagnostic / therapeutic sacroiliac joint injection, the patient's pain level is assessed by having the patient perform activities that would usually provoke pain. The percentage of pain relief is documented and a physical examination is performed. A positive response is defined as at least 75 percent improvement of the patient's painful activity related symptoms. If a second diagnostic injection is positive, then the sacroiliac joint is considered the likely source of the patient's painful symptoms.

Although individual recommendations may differ, depending on the patient’s situation and the physician’s preference, the following are typical:

  • Drink plenty of water to help flush the dye used for fluoroscopy out of the body.
  • Do not perform excessive activities on the day of the procedure, especially if sedation was administered.
  • A list of signs or symptoms that warrant immediate medical attention will often be provided to the patient as a part of the discharge procedure.
