Sacroiliac (SI) joint pain is felt in the low back and may spread to the groin and legs. There is one joint on the right side of the spine and one on the left. They are held together with strong bands of fiber called ligaments. The joints help reduce impact on the spine during things like walking.
The doctor may also use a nerve block to make sure the pain is coming from the SI joint. Medicine that blocks pain is injected near the SI joint. If pain stops, then the joint is confirmed as the cause.
Underlying causes will be treated. The goal of treatment is to manage symptoms and give the joints time to heal. Choices are:
Initial care, such as resting the back and using cold or warm packs
Medicine to ease pain and swelling, such as:
Over the counter pain relievers, such as ibuprofen
Prescription pain relievers
Steroid injections into the sacroiliac joint
Physical therapy to improve strength and range of motion
Decreasing stress on the back will lower the chance of SI joint pain. This may be done through:
Exercising regularly to keep muscles strong
Using proper techniques for bending, lifting, or playing sports
