Sacroiliac pain occurs in the lower back, right where the spine meets the pelvis. It can be confused with sciatica because the pain sometimes radiates to the buttocks or leg, but its origin is usually in the sacroiliac joint. Identifying its symptoms helps guide diagnosis and treatment.
What is sacroiliac pain and where exactly is it felt?
Sacroiliac pain is discomfort in the sacroiliac joint, where the base of the spine connects to the pelvis. This joint bears the weight of the body from the spine to the lower extremities. When it becomes inflamed or irritated, it causes pain in the lower back, usually felt on one side.
The pain may radiate to the hip, buttock, or inner thigh. Some patients describe a mild burning sensation, while others describe it as a sharp, debilitating pain.
What are the symptoms of a sacroiliac injury?
The symptoms of a sacroiliac joint injury can vary, but the most common are lower back and buttock pain. Other symptoms may include stiffness, a feeling of pelvic blockage, or discomfort when putting weight on one leg.
In many cases, the pain worsens with everyday activities such as walking, driving, lifting heavy objects, or sitting for long periods. This is why it's easy to mistake it for other lower back problems if it's not properly diagnosed.
Lower back, buttock, groin and leg pain: common signs
Lower back pain is the most common symptom, especially if it's felt on only one side of the back. Deep pain in the buttocks, groin or thigh discomfort, and pain on the outside of the hip are also frequent.
Other symptoms may include stiffness upon standing, difficulty climbing stairs, a feeling of pelvic instability, and leg weakness. The pain may also worsen after prolonged activity or repetitive movements.
Why does the sacroiliac joint become inflamed or irritated?
The sacroiliac joint can become inflamed for several reasons. Most commonly, it is due to repetitive movements, prolonged poor posture, changes in gait, or pelvic misalignment.
It can also become inflamed after a fall, an accident, or an injury directly to the area. Pregnant women are also at higher risk because hormonal changes can loosen the ligaments, and the pelvis, as it adapts to the pregnancy, becomes more unstable, especially in that joint.
Overloads, falls, pregnancy, osteoarthritis and gait problems
Overuse is a very common cause of sacroiliac pain, especially in athletes, people who lift heavy objects, or patients who spend many hours on their feet, as all of these factors directly affect the area. Falls onto the buttocks or direct blows to the pelvis can also cause inflammation in the joint, leading to discomfort.
During pregnancy, hormonal changes and increased pelvic mobility can contribute to sacroiliac pain. Other conditions such as osteoarthritis, gait abnormalities, leg length discrepancy, or certain muscle imbalances could also increase tension in this area.
How to differentiate sacroiliac pain from sciatica?
Sacroiliac pain is felt in the lower back, near the buttocks, and can radiate to the hip, groin, or thigh. Although the pain may travel down the leg, it does not always follow the path of the sciatic nerve.
In sciatica, the pain most commonly radiates from the back down the buttock, leg, and even the foot, and may be accompanied by tingling, numbness, or weakness. If the pain spreads or neurological symptoms are present, it is important to consult a doctor.
Do you need a second opinion about a spinal problem or traumatic injury?
We review your MRIs, reports, and tests to give you a clear diagnosis and an appropriate treatment plan.
Request a second medical opinionWhat tests help diagnose sacroiliac pain?
The professional will perform specific physical tests to evaluate the sacroiliac joint, such as the Patrick test, the Gaenslen test, and the pelvic compression test. These tests aim to reproduce the pain or detect abnormal movement in the joint in order to establish an accurate diagnosis.
To confirm the diagnosis, an MRI or CT scan may be ordered to rule out other injuries. Generally, an X-ray is sufficient to detect changes in the joint.
What conservative treatments are used for sacroiliac pain?
Conservative treatments are the first step and very effective if the condition is uncomplicated. Specialized physiotherapy, therapeutic exercises to stabilize the joint, and changes in posture and daily habits should be more than enough in a typical case.
Physiotherapy, therapeutic exercise and changes in postural habits
Physical therapy can greatly help reduce pain, improve mobility, and strengthen the muscles that stabilize the pelvis. Therapeutic exercise should be tailored to each patient to avoid movements that increase irritation.
Postural changes are also important and should be practiced to develop good habits over time. Alternating positions, avoiding prolonged periods of sitting or standing, using proper lifting technique, and improving daily ergonomics all help reduce stress on the sacroiliac joint.
When are injections considered for sacroiliac pain?
Injections are considered when sacroiliac pain persists despite treatment or when it limits mobility. They are also used when the specialist suspects that the sacroiliac joint is the primary source of the pain.
This procedure combines an anesthetic and an anti-inflammatory to relieve local inflammation. It should always be prescribed by a doctor, especially if physical therapy, medication, and lifestyle changes have already been tried without clear improvement.
What exercises can help stabilize the pelvis and lower back?
The most effective exercises are those that strengthen the deep abdominal muscles, glutes, hips, and lower back to improve pelvic stability and reduce strain on the area.
These exercises may include core activation, glute bridges, gentle hip mobility exercises, and progressive lumbopelvic stability work. Always do this under professional supervision, especially if the pain increases or radiates down the leg.
When should you see a specialist for persistent sacroiliac pain?
It's important to consult a professional if the pain persists for more than two weeks, is very intense, radiates down the leg, or if there is muscle weakness. An orthopedic specialist or physical therapist can diagnose the problem and design a personalized treatment plan; furthermore, early intervention offers better results.
