What to expect from sacroiliac joint injection for sacroiliac joint dysfunction

You usually lie face down while the skin is cleaned and numbed. Imaging guidance helps the clinician position the needle accurately near the sacroiliac joint. You may feel pressure or a brief sting. A local anaesthetic can provide short-term numbness, while an anti-inflammatory medicine may take longer to have an effect. Relief is not always immediate or complete, and the response can help your clinician plan next steps.

Sacroiliac joint dysfunction can overlap with pain from the lower back, hip, or surrounding muscles. The injection is one part of an assessment and does not replace movement assessment or rehabilitation.

Tell the clinic about allergies, infection, diabetes, blood-thinning medicines, pregnancy, and previous injection reactions. Ask whether any medicine should be paused; do not change it without instructions. Arrange transport if your leg feels numb or weak afterward. Keep activity light for the rest of the day, record changes in pain and movement, and follow the clinician’s plan for returning to exercises.

Call the clinic for persistent or worsening numbness, new weakness, increasing redness or drainage at the injection site, or pain that escalates rather than settles. Seek urgent care for fever with severe back or pelvic pain, loss of bladder or bowel control, or new numbness around the groin.

Ask what the injection is intended to test or treat, which medicines it contains, when to expect an effect, how to record your response, and when physiotherapy should restart. Confirm medication instructions, driving advice, and the next option if relief is limited.
