Sacroiliac Joint Pain

Sacroiliac joint pain is felt in the lower back and buttocks area of the body. The joints, there are two, are located where the lower spine meets the pelvis.

This type of joint pain is commonly overlooked because the pain is felt in the lower back area, an area that is commonly aggravated for many differing reasons.


There are a few factors that can contribute to sacroiliac joint pain. Like any joint in the body, cartilage surrounds the joint to allow the bones to glide smoothly. If arthritis attacks this joint and the cartilage wears down, the patient will experience pain.

When the body of a woman prepares for pregnancy, the hips will widen allowing the sacroiliac joint more range of motion which can cause discomfort and pain.

If the joint becomes inflamed because of an infection, a patient will experience pain. Trauma, direct injury, twisting and bending can also aggravate the joint and cause pain.


The most common symptoms of sacroiliac joint pain are pain in the lower back, buttocks, pelvis, hip and groin areas. Pain can also be felt radiating down the leg and the lower spine can become stiff.
