Sacroiliac (SI) Joint Sprain Causes, Symptoms & Treatment
Sacroiliac (SI) joint sprain causes pain in the lower back and hip region, often triggered by sudden twisting, heavy lifting, or direct impact. It occurs when the ligaments supporting the SI joint become overstretched or torn, leading to inflammation, instability, and discomfort. Common symptoms include localized pain, stiffness, and difficulty moving. Treatment usually involves rest, targeted physical therapy, pain management, and in severe cases, medical procedures to restore joint stability and function.

The sacroiliac (SI) joints connect the two iliac bones of the pelvis to the sacrum, the triangular bone at the base of the spine. These joints help support body weight and allow limited rotation of the hips and pelvis. Strong ligaments hold the SI joints in place, providing stability while allowing slight movement.
When these ligaments are stretched, irritated, or torn from repetitive motion, sudden twisting, heavy lifting, or trauma, pain and inflammation can develop.
This is common among athletes and people involved in physically demanding activities.
What causes Sacroiliac (SI) Joint Sprain?
A sacroiliac (SI) joint sprain can result from direct trauma to the pelvis, such as a fall or collision during sports. Overuse from repetitive twisting movements, common in many athletic activities, can also lead to injury. In some cases, SI joint dysfunction develops gradually without a clear cause.
- How the Injury Occurs: Direct impact to the pelvis or repetitive twisting motions during activity can overstretch or tear the ligaments supporting the SI joint, causing pain and instability.
- Common Everyday Causes: This condition may develop in individuals who lift heavy objects, stand unevenly, or perform repetitive bending and twisting in daily or occupational tasks.
Sports commonly linked to SI joint sprain include:
- Hockey: Rapid direction changes and body contact place repeated stress on the SI joints.
- Football: High-impact tackles and sudden twisting motions can strain the supporting ligaments.
- Ice Skating: Frequent rotational movements and jumps increase pressure on the joints.
- Gymnastics: Repetitive bending, twisting, and hard landings challenge joint stability.
- Tennis: Quick side-to-side movements and powerful rotational swings may overstretch the ligaments around the joint.
Symptoms
Patients with a sacroiliac (SI) joint sprain often feel pain in the lower back or upper hip area. Symptoms may include:
- Pain that radiates into the upper thigh, groin, or sometimes the buttocks
- A feeling of hip or pelvic instability, hip tendonitis symptoms, weakness, or “giving way”
- Increased discomfort while standing, walking, running, or twisting
- Relief of pain when lying down, sitting, or resting
- Stiffness or limited range of motion in the lower back and hips
- Tenderness when pressing over the SI joint
The intensity of symptoms can vary and may interfere with sports or activities that involve rotational movement, quick direction changes, or repetitive twisting.
When to see a doctor
Patients with ongoing symptoms of a sacroiliac (SI) joint sprain should seek medical evaluation. Diagnosis is usually made through an examination, during which the clinician observes the condition of the hips and legs to locate the source of pain and assess joint function.
In some cases, imaging tests such as X-rays, CT scans, or MRI scans may be recommended to confirm the diagnosis or rule out other causes of lower back, piriformis syndrome, sacroiliac, or hip pain. Early assessment allows for timely treatment and helps prevent chronic discomfort or joint instability.
Non-operative treatment
Initial treatment for sacroiliac (SI) joint sprains focuses on avoiding activities that worsen pain, such as running, lifting, or twisting. Other approaches include:
- Applying a cold compress to painful areas can help you get SI joint pain relief and reduce inflammation
- Taking nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, for pain relief
- Receiving corticosteroid injections into the SI joint, often guided by X-ray, to reduce inflammation and discomfort
- Performing stretching and stabilizing exercises to relieve pain and improve strength and flexibility
A structured exercise program can support recovery. For guidance, see the provided PDF of the recommended exercises.

Recovery
With proper rest, targeted treatment, and a gradual return to activity, patients with a sacroiliac (SI) joint sprain can usually expect improvement within several weeks. Recovery time varies depending on the severity of the injury and the individual’s activity level.
A structured rehabilitation plan, often including physical therapy, stretching, and strengthening exercises, is important to restore joint function, improve stability, and prevent recurrence. Your healthcare provider will guide your recovery, monitor progress, and advise when it is safe to resume sports or daily activities, ensuring the best long-term outcomes.
