Lower back or hip pain can be frustrating, especially when it’s hard to figure out where it’s coming from. One possible cause is sacroiliac joint (SI) pain, also called SI joint dysfunction. The SI joint connects your spine to your pelvis and helps transfer weight between your upper body and legs. When the sacroiliac joint becomes irritated or inflamed, also known as sacroiliitis, it can cause pain in your lower back, hips or buttocks.
The good news? There are many treatment options. Here’s what you need to know about sacroiliac joint pain and how to treat it.
Start with simple treatments
Most people begin with basic steps to ease pain and swelling. Over-the-counter pain medicines like ibuprofen or naproxen can help bring down joint inflammation. Cold packs may reduce swelling in the first couple of days, while heat packs can relax tight muscles after that.
It’s also important to keep moving. While you may need a little rest at first, staying still too long can make stiffness worse. Gentle stretching or short walks can help you feel better.
Physical therapy can help
If pain continues, physical therapy is a helpful next step. A physical therapist will show you stretches and exercises that strengthen your core. These muscles support your back and pelvis, which can take pressure off your sacroiliac joint and reduce pain over time.
Therapy may also include learning how to stand, sit and move in a way that keeps your back safe. With practice, many people see real improvements in how they feel.
Injections for stronger relief
Sometimes, your doctor may recommend a shot into the sacroiliac joint. This injection usually contains medicine to reduce swelling and numb the pain. It can bring fast relief and also help confirm that the SI joint is the source of your pain.
Relief from an injection can last for weeks or even months. This treatment is often used when rest and therapy don’t provide enough relief on their own.
Other treatment options
If your pain doesn’t go away, there are more options your doctor might suggest.
- Radiofrequency ablation
A special tool uses heat to block pain signals from the nerves near the SI joint. - Minimally invasive surgery
In rare cases, the sacroiliac joint may be fused so it moves less and causes less pain. - Some people, with chronic sacroiliac pain, also try chiropractic care, massage therapy or acupuncture for extra support.
Not all treatments work the same for everyone, so talk to your orthopedic spine specialist about what might be right for you.
Simple lifestyle changes
Even small changes in your daily routine can help manage sacroiliac joint pain. Try to:
- Keep a healthy weight to reduce pressure on your back
- Avoid heavy lifting or twisting suddenly
- Do low-impact exercises like walking, swimming or biking
- Sit in supportive chairs and wear shoes with good support
These habits can protect your back and reduce the risk of lower back and pelvic joint pain from returning.
Keep track of what works
It’s a good idea to write down what makes your pain better or worse. You can track how you feel after trying certain treatments or exercises. Share your notes with your doctor at each visit. This helps your care team adjust your plan and find what works best.
Sacroiliac joint pain can be uncomfortable, but there are many ways to treat it. Starting with simple steps like rest, medicine and therapy can make a big difference. If you need more help, injections or other treatments are available. Talk to your doctor to find the right plan for you.
