Sacroiliac Joint Injections in Phoenix, Mesa, Scottsdale & Peoria, Arizona
What Are Sacroiliac (SI) Joint Injections?
The sacroiliac joints sit at the base of your spine, connecting the sacrum to the pelvis. These small but powerful joints absorb shock, support your upper body, and provide stability with every step you take. When irritated or inflamed, they can cause persistent lower back, hip, or buttock pain that often radiates down into the legs.
A sacroiliac joint injection is a safe and effective treatment designed to both diagnose and relieve SI joint pain. By delivering a combination of numbing medication and anti-inflammatory steroid directly into the joint, inflammation is reduced and mobility is improved. At Mountain View Headache & Spine Institute, with offices in Phoenix, Mesa, Scottsdale, and Peoria, we use SI joint injections to help patients return to daily life with less pain and greater freedom of movement.
Why Would I Need a Sacroiliac Joint Injection?
SI joint pain is more common than many realize—it can be triggered by arthritis, injury, pregnancy, or simply the strain of daily activity. If left untreated, this discomfort can make sitting, standing, walking, or even sleeping a challenge.
You might benefit from a sacroiliac joint injection if you:
- Experience lower back or hip pain that worsens with standing or climbing stairs
- Feel pain in the buttocks or upper legs that mimics sciatica
- Notice stiffness or difficulty sitting for long periods
- Have pain that has not improved with physical therapy, stretching, or medications
For many Arizona patients, SI joint injections provide both immediate relief and valuable diagnostic information to confirm the SI joint as the source of pain.
How Does the Procedure Work?
SI joint injections are performed in-office and typically take less than 20 minutes:
- Preparation – The skin is cleaned and numbed.
- Guided Placement – Using live X-ray (fluoroscopy), the physician precisely guides a thin needle into the sacroiliac joint.
- Medication Delivery – A small amount of numbing medicine and steroid is injected into the joint space.
- Relief – Patients often notice reduced pain within minutes to hours as inflammation decreases.
Are There Side Effects?
Sacroiliac joint injections are considered very safe. Common side effects include:
- Mild soreness or bruising at the injection site
- Temporary numbness or weakness in the leg
- Rare but possible infection or bleeding
Most patients resume normal activity the same day.
How Do I Know If I Need a Sacroiliac Joint Injection?
If your lower back or hip pain worsens with movement and hasn’t improved with conservative care, you may be a candidate. SI joint injections not only provide relief but also confirm whether the sacroiliac joint is the true source of your discomfort.
At Mountain View Headache & Spine Institute, our specialists take time to understand your symptoms and create a tailored plan—whether that means injections, physical therapy, or a combination of treatments.
How Well Do Sacroiliac Joint Injections Work?
Many patients report immediate improvement in pain and function, while others notice steady relief over several days. Results may last weeks to months, and when paired with strengthening exercises or therapy, SI joint injections can support long-term stability and reduced pain.
