What Happens If Sacroiliac Joint Dysfunction Is Not Treated?

The sacroiliac joints connect the base of the spine with the pelvis and transfer load between the trunk and legs. Irritation or altered movement there may cause pain in one buttock or the lower back, sometimes spreading toward the hip or thigh. A person may shorten their stride, avoid stairs, shift weight while standing or brace the trunk during turning. Those adaptations can place extra demand on the back, hip and surrounding muscles. Symptoms may become recurrent and reduce confidence with exercise, work, sleep or prolonged sitting, although the course differs between people.

Arrange an assessment so the source of pain is checked against other back, hip and nerve conditions. Physiotherapy can work on pelvic and trunk strength, hip mobility, movement habits and gradual return to activity. Manual therapy may be used alongside active rehabilitation when appropriate. If symptoms remain limiting after a suitable plan, a clinician may discuss a sacroiliac joint injection as a diagnostic or treatment option. Avoid repeatedly forcing painful twisting or lifting while maintaining comfortable movement.

Seek medical review for buttock or lower-back pain that persists, worsens or limits walking, sitting or sleep. Get urgent help for new loss of bladder or bowel control, numbness around the groin, progressive leg weakness, fever with severe back pain, or pain after major trauma. Prompt assessment is also needed when pain is accompanied by unexplained weight change or a generally unwell feeling.

How confident are we that the sacroiliac joint is the pain source? Which movements or tests support that view? What strengthening and mobility work should I start? Would manual therapy or an injection add value? What warning symptoms should change the plan?
