Sacroiliac Joint Pain: The Back Problem Often Blamed on the Wrong Structure

Low back pain is often blamed on the spine, but that is not always where the problem begins. The sacroiliac, or SI, joint connects your spine to your pelvis, and it can produce pain that feels very similar to other back conditions. That is why SI joint pain physiotherapy starts with identifying the true source of your symptoms before building a treatment plan.
If back or pelvic pain is making everyday activities more difficult, consider booking an assessment at Peach Physiotherapy.
A Closer Look at SI Joint Pain
Understanding the Anatomy of Sacroiliac Joint Pain
You have two SI joints, one on each side of your lower back. These joints help connect your upper body to your legs and allow forces to move through your body when you walk, climb stairs, lift, or change direction.
Although the SI joints move only a small amount, they play an important role in keeping the pelvis and lower back working together. When the joints become irritated or do not move well, even simple activities can become uncomfortable.
Common Drivers of Sacroiliac Joint Pain Discomfort
SI joint pain can begin after a specific event or develop slowly over time. Common causes include:
- Repeated bending or lifting
- Slips or falls
- Pregnancy and changes in the pelvis
- Weakness in the hips or trunk
- Reduced movement in nearby joints
- Changes in walking after a previous injury
Because these symptoms often resemble a muscle strain or disc problem, many people are surprised to learn the SI joint is contributing to their discomfort.
What an SI Joint Problem Feels Like Day to Day
Pain from the SI joint is usually felt on one side of the lower back or near the buttock.
You may notice discomfort when you:
- Stand for long periods
- Walk uphill or climb stairs
- Roll over in bed
- Get in or out of a vehicle
- Stand up after sitting for a while
Some people also notice pain spreading into the hip or upper thigh. This can make it difficult to tell where the problem is coming from without an assessment.
Treating SI Joint Pain
Everyday Steps That Support SI Joint Pain Physiotherapy
There are several simple ways to reduce unnecessary stress on the SI joint while waiting for an assessment.
- Change positions regularly instead of sitting or standing for long periods.
- Use both legs evenly when standing whenever possible.
- Avoid carrying heavy loads on one side of your body.
- Stay active with comfortable daily movement instead of avoiding activity altogether.
These habits may help reduce irritation, but they do not replace finding the cause of the problem. SI joint pain physiotherapy focuses on improving how the pelvis, hips, and lower back work together during everyday movement.
What an Evaluation at Peach Physiotherapy Focuses On
A SI joint pain physiotherapy assessment looks at how your body moves as a whole rather than focusing on one painful area. Your physiotherapist may assess:
- Movement of the lower back, hips, and pelvis
- Strength through the hips and trunk
- Walking and standing mechanics
- Everyday movements that reproduce your symptoms
These findings help determine whether SI joint dysfunction is contributing to your pain or whether another condition should also be considered.
How Personalised Care Supports Daily Function
No two people experience SI joint pain the same way. Your treatment plan should reflect your symptoms, daily activities, and goals. Depending on your assessment, your programme may include:
- Exercises to improve strength and stability
- Movement retraining for daily activities
- Hands-on treatment to improve joint mobility when appropriate
- Education on lifting, bending, and movement habits
Throughout SI joint pain physiotherapy, your physiotherapist will adjust your programme as your movement changes, helping you build confidence with everyday activities at a pace that suits you.
Take the First Step Toward Better Movement
Pain around the lower back and pelvis is not always caused by the spine. Understanding where your symptoms are coming from is an important step toward choosing the most appropriate care.
If your back or pelvic pain has been limiting your daily activities, the team at Peach Physiotherapy can help you better understand what is contributing to your symptoms and discuss treatment options that match your goals and lifestyle.
