Inflamed Sacroiliac Joint: Symptoms and Solutions
Léa Guido
What is the sacroiliac joint?
The sacroiliac joint connects the base of the spine (the sacrum) to the pelvis. Although it moves very little, it plays a key role in transferring weight from the trunk to the legs, so any disruption there can cause pain and a feeling of instability.
Common symptoms
Pain is usually felt in the lower back, near the buttock, and can radiate toward the hip or the back of the thigh. It often gets worse with prolonged standing, climbing stairs, standing up from a chair, or twisting the trunk.
Common causes of inflammation
It can develop from overload (repetitive strain or poor posture), pregnancy, a fall or impact, or leg-length differences that alter the mechanics of the pelvis.
How chiropractic care can help
A chiropractic examination helps identify whether the joint is restricted or overly mobile, so care can be tailored to each case. Specific pelvic adjustments, combined with stabilization exercises, typically bring gradual relief and help prevent flare-ups.
Frequently asked questions
How is sacroiliac pain different from sciatica? Sacroiliac pain tends to stay more localized in the lower back and buttock, while sciatica more often radiates down the whole leg.
Should I rest completely? No. Prolonged rest can actually increase stiffness; it's better to stay moving within your pain limits.
How long does it take to improve? With appropriate care, many patients notice improvement within a few weeks, though it depends on the cause and how long it's been present.
When should I see a professional? If the pain is severe, doesn't improve over several days, or comes with tingling or leg weakness.
