The sacroiliac (SI) joint connects the spine to the pelvis and helps transfer force during walking, standing, and lifting. When the SI joint becomes irritated or unstable, it can cause low back pain, buttock pain, and discomfort that may feel similar to sciatica. At Mountain View Pain Center, we help identify what’s driving your symptoms and build a plan to reduce pain and restore comfortable movement.
When to Seek Urgent Care
Seek urgent evaluation if you have new or worsening weakness, loss of bowel or bladder control, saddle numbness, severe unrelenting pain after trauma, fever/chills, or rapidly worsening numbness/tingling.
SI joint pain can overlap with low back pain, hip pain, and sciatica-like symptoms, so we focus on clarifying the source. Your visit may include a review of symptom triggers, movement testing, and assessment of the low back, hips, and pelvis. We may use specific exam maneuvers that help determine whether the SI joint is contributing to your pain. If symptoms include radiating pain, numbness, or tingling, we may also perform a basic neurologic screen. We also check for red flags to determine whether imaging or referral is appropriate.
At Mountain View Pain Center, our multidisciplinary team combines evidence-based care to reduce irritation and improve pelvic stability:
Targeted diagnostic injections and image-guided procedures when appropriate to reduce inflammation and help confirm pain sources.
Movement-based care to improve hip mobility, strengthen the core and glutes, and build pelvic stability for long-term results.
Hands-on care to support joint mobility and reduce muscle tension, tailored to your symptoms and comfort.
A natural option to support pain relief and relaxation, often combined with your broader plan.
Every clinic below has Chiropractic, Physical Therapy, Acupuncture and Pain Management on one chart, so care can move between them without a new referral.

SI joint pain is often felt on one side of the low back or buttock, sometimes referring into the hip, groin, or upper thigh.
Yes. SI joint irritation can refer pain into the buttock and upper leg and may feel similar to sciatica. We evaluate symptoms to determine whether nerves are involved.
Diagnosis often involves your symptom pattern, exam findings, and targeted testing. In some cases, an image-guided diagnostic injection can help confirm the SI joint as a pain source.
Many people improve with a coordinated plan that builds hip mobility and pelvic stability—often combining PT, Chiropractic care, Acupuncture, and, when appropriate, Pain Management procedures.
Not always. If your symptoms or exam suggest imaging would help guide care, we’ll recommend the appropriate next step.
Often, no. Some insurance plans require a referral or authorization—if you’re unsure, we can help verify.
A group of examination tests point to the joint rather than the spine, and where it is still unclear a diagnostic injection settles it. Getting this right matters, because treating the wrong structure is why sacroiliac pain often drags on.
It commonly does, because the ligaments around the joint loosen. Care during and after pregnancy is aimed at the muscles that have to take up that slack.
