Sacroiliac Joint Pain: Causes, Symptoms

Understanding the Sacroiliac Joint

The sacroiliac joint (SI joint) plays an important role in connecting the spine to the pelvis. This joint supports your upper body’s weight and helps absorb shock during walking, running, or lifting. Because of its position, the sacroiliac joint can become a source of pain when it is irritated or strained.

Many people who experience discomfort in the lower back, hips, or buttocks may actually be dealing with issues related to the sacroiliac joint. Although the pain can feel similar to other spine or hip problems, the source often lies in the SI joint itself.

Why Do People Experience Sacroiliac Joint Pain?

Sacroiliac joint pain can affect a wide range of individuals. Athletes may develop it due to repetitive movements, while people with sedentary lifestyles may notice stiffness that contributes to joint irritation. Even everyday activities such as climbing stairs, sitting for long periods, or carrying heavy loads can put pressure on the SI joint.

For example:

• A runner may feel pain near the buttocks after long training sessions.
• A person who sits at a desk for hours could experience stiffness around the lower back and hips.
• Parents who frequently lift children may strain their sacroiliac joint over time.

Because this pain can overlap with symptoms of other conditions, a careful assessment is important to guide appropriate care.

What Causes Sacroiliac Joint Pain and What Are the Symptoms?

The causes of sacroiliac joint pain are varied. Some are linked to lifestyle factors, while others come from injuries or structural issues.

Common Causes:

• Repetitive movements such as running, jumping, or lifting heavy objects.
• Poor posture during prolonged sitting or standing.
• Pregnancy, which increases stress on the pelvic region due to hormonal changes and added weight.
• Injury or trauma, such as a fall directly onto the lower back or buttocks.
• Degeneration of the joint over time, which can occur with ageing.

Common Symptoms:

• Pain on one or both sides of the lower back.
• Discomfort in the buttocks or back of the thighs that can feel sharp or achy.
• Stiffness when getting up from a chair or out of bed.
• Pain that worsens with climbing stairs or standing for long periods.
• A feeling of instability or weakness in the pelvic region.

These symptoms may interfere with daily activities, but with the right strategies, many people are able to return to normal movement.

How Do You ease Sacroiliac Joint Pain?

Managing sacroiliac joint pain usually involves a combination of lifestyle adjustments, non-surgical interventions, and guided exercise.

Here are some approaches often recommended by medical professionals:

1. Activity Modification
   Reducing repetitive stress on the joint, such as limiting long runs or heavy lifting, can help reduce irritation.
2. Strengthening and Stretching Exercises
   Focused exercises that improve stability in the lower back, pelvis, and hips may ease stress on the sacroiliac joint.
3. Supportive Devices
   In some cases, belts or braces designed to stabilise the pelvis can reduce movement at the joint and improve comfort.
4. Ultrasound-Guided Injections
   When pain persists, non-surgical options like image-guided injections may be considered to relieve inflammation. These procedures are carried out in a controlled clinical setting by trained specialists.
5. Education and Prevention
   Understanding posture, body mechanics, and safe movement techniques can prevent flare-ups and allow individuals to manage symptoms better over time.
