Where it is felt and why it's confused with a disc
Sacroiliac pain is usually felt in the lower back, on one side, over the buttock, and can spread down to the thigh. Because it is near the low-back region, it is often confused with a herniated disc. Examination with specific tests helps distinguish the true source.
Conservative approach first
Physiotherapy, pelvic stabilization exercises, posture adjustment and medication are the first step and help many patients. When pain persists, image-guided procedures become an option.
Injection and radiofrequency (RF)
An image-guided injection into the sacroiliac joint can confirm the source of pain and provide relief. If relief is clear but temporary, RF denervation of the nerves carrying the pain can give a longer-lasting effect — without an incision.
What you should know
These procedures aim to control pain, not to 'repair' the joint; the effect can last months and can be combined with physiotherapy. Correct patient selection — that the pain truly comes from the sacroiliac joint — is the key to success.
