Back pain is something most people experience at some point. It improves with rest or simple home care. Sometimes, the source of the discomfort is not the spine itself. It comes from the sacroiliac joints, where the lower spine connects to the pelvis. When these joints become irritated or do not move as they should, they can cause Sacroiliac joint pain.
Many people assume they have a muscle strain or a disc problem. In reality, SI joint pain may result from inflammation, injury, or Sacroiliac joint dysfunction. The pain can affect the lower back, buttocks, hips, and occasionally the upper leg. Treatment depends on the underlying cause. Many people recover with physiotherapy, exercise, and lifestyle changes, while others may benefit from medication or Interventional pain management procedures.
This article mentions the causes, symptoms, diagnosis, and treatment options for Sacroiliac joint pain, helping readers understand when to seek medical advice and how the condition can be effectively managed.
Understanding the Sacroiliac Joints
Everyone has two sacroiliac joints, located on either side of the pelvis. These joints connect the sacrum, the triangular bone at the base of the spine, to the pelvic bones.
Although they have only a small range of movement, they perform an important job. Every time you stand, walk, bend, or climb stairs, these joints help transfer body weight from the upper body to the legs. They also provide stability and absorb some of the forces created during movement. When their movement changes or inflammation develops, pain may follow.
What Can Lead to Sacroiliac Joint Pain?
There is rarely one single cause of SI joint pain. In many cases, several factors contribute over time.
Age-Related Joint Changes
Cartilage wears down, flexibility decreases, and stiffness becomes more noticeable. These changes can contribute to lower back pain, after standing or walking for long periods.
Injury or Trauma
Falls, sporting injuries, or motor vehicle accidents can place sudden stress on the pelvis. Even if the injury seems minor, it may affect how the joint moves. Some people notice pain straight away, while others develop symptoms weeks later.
Pregnancy and Hormonal Changes
Pregnancy naturally places extra pressure on the pelvis. Hormones also relax the supporting ligaments to prepare the body for childbirth. These changes can reduce joint stability and contribute to Sacroiliac joint dysfunction. Although symptoms improve after delivery, some women continue to experience discomfort.
Arthritis and Inflammatory Conditions
Both osteoarthritis and inflammatory conditions can affect the sacroiliac joints. Ongoing inflammation may lead to stiffness, tenderness, and pain that becomes worse after sitting or resting for long periods.
Changes in Walking or Body Mechanics
Sometimes the problem develops because the body is moving differently. Weak muscles, poor posture, uneven leg length, or altered walking patterns can place extra stress on the pelvis. Over time, this repeated strain may trigger Sacroiliac joint pain.
Previous Spinal Surgery
Some people develop sacroiliac joint problems after spinal surgery. Changes in spinal movement may increase pressure on the pelvis, making the joints work harder than before.
Common SI Joint Symptoms
The symptoms of Sacroiliac joint pain overlap with other causes of lower back pain, which makes diagnosis challenging.
Common SI joint symptoms include:
● Pain on one side of the lower back
● Buttock pain
● Hip discomfort
● Pain that spreads into the upper thigh
● Increased discomfort when standing or climbing stairs
● Stiffness after sitting for a long time
● Difficulty changing positions or walking comfortably
Some people experience constant discomfort, while others notice that symptoms come and go depending on activity levels.
How Is Sacroiliac Joint Pain Diagnosed?
Doctors combine several assessment methods rather than relying on one test.
Medical History
The first step involves discussing your symptoms, daily activities, previous injuries, and anything that makes the pain better or worse.
Physical Examination
Your doctor will assess movement in the lower back, hips, and pelvis. Special movement tests may help determine whether the sacroiliac joint is contributing to your symptoms.
Imaging Tests
X-rays, CT scans, or MRI scans may be used to rule out fractures, arthritis, disc problems, or other causes of chronic back pain.
Diagnostic Injections
If the diagnosis remains uncertain, an image-guided injection may be recommended. Temporary pain relief after the injection suggests that the sacroiliac joint is likely to be the main source of discomfort.
What Treatment Options Are Available?
The right Sacroiliac joint treatment depends on the cause of pain, how long it has been present, and how much it affects everyday life. Some people respond well to simple measures, while others may need specialised care. Treatment begins with conservative approaches before moving to advanced procedures if symptoms continue.
Conservative Treatment
- Activity Modification
Small changes to your daily routine can reduce stress on the sacroiliac joints. Limiting heavy lifting, avoiding long periods of standing, and taking regular breaks during repetitive activities may ease SI joint pain. These adjustments are temporary and can support the healing process.
2. Physiotherapy
Physiotherapy is the most common treatment for Sacroiliac joint dysfunction. A physiotherapist can identify movement problems, improve joint stability, and recommend exercises that strengthen the muscles supporting the lower back and pelvis.
3. Exercise Programs
Gentle exercise helps maintain flexibility and improve muscle strength. Walking, stretching, and core-strengthening exercises are recommended because they support the joints without placing unnecessary stress on them. The program should match your symptoms and fitness level, so professional guidance is helpful.
4. Medication
Pain-relieving or anti-inflammatory medication may be recommended to manage symptoms during painful periods. The type of medicine depends on your condition and medical history, so it should always be taken according to your healthcare provider's advice.
Interventional Pain Management
If conservative care does not provide enough relief, your doctor may discuss additional Pain management options.
Image-guided injections place medication directly into the affected sacroiliac joint to reduce inflammation. These injections can also help confirm whether the joint is the source of the pain.
Radiofrequency treatment uses controlled heat to interrupt pain signals from the nerves around the joint. Some people experience longer-lasting relief, although results vary.
For ongoing Chronic back pain, a specialist may recommend Interventional pain management as part of an individual treatment plan. This approach may combine different procedures with physiotherapy, exercise, and lifestyle advice to improve movement and daily function.
When Is It Time to See a Healthcare Professional?
Back pain improves with rest, but symptoms that continue or become worse should be assessed by a healthcare professional.
It is worth seeking medical advice if you have:
• Persistent lower back pain lasting several weeks
● Ongoing SI joint symptoms that interfere with daily activities
● Pain that does not improve with home care
● Difficulty walking, standing, or climbing stairs
● Pain affecting your work, sleep, or quality of life
● Signs of Chronic back pain that continue to return
Early assessment can help identify the cause and allow appropriate Sacroiliac joint treatment to begin before symptoms become more difficult to manage.
Conclusion
Sacroiliac joint pain is a common but overlooked cause of Lower back pain. Because its symptoms can resemble muscle strain, arthritis, or spinal conditions, it is important not to rely on symptoms alone. Understanding the common SI joint symptoms and the factors that contribute to Sacroiliac joint dysfunction can make it easier to seek the right care.
The good news is that a range of Sacroiliac joint treatment approaches is available. Many people improve with physiotherapy, exercise, activity changes, and medication, while others may benefit from advanced pain management options, including Interventional pain management. If SI joint pain continues or develops into chronic back pain, speaking with a healthcare professional can help you receive an accurate diagnosis and a treatment plan that suits your individual needs.
