More About Your Problem
The main purpose of the joint is to connect the spine and the pelvis. As a result, there is very little movement at the SIJ.
Major reasons for pain around the SIJ include:
Although, SIJ pain can be caused by trauma, this type of injury more often develops over a long period.
What to Expect
Symptoms of SIJ dysfunction include:
Your doctor may move your legs and hips around in different positions to help diagnose a SIJ dysfunction. You may also need to have x-rays or a CT scan.
Follow these steps for the first few days or weeks after your injury or when starting treatment for SIJ pain:
For pain, you can use ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), or acetaminophen (Tylenol). You can buy these medicines at the store without a prescription.
If this is a chronic problem, your doctor may prescribe an injection to help with pain and inflammation. The injection can be repeated over time if needed.
Keep activity to a minimum. The more time the injury has to rest, the better. For support during activity, you can use a sacroiliac belt or lumbar brace.
Physical therapy is an important part of the healing process. It will help relieve pain and increase strength. Talk to your doctor or physical therapist for exercises to practice.
