What causes SI joint pain?

ANSWER

The pain starts when your SI joint gets inflamed. There are several reasons it could happen. You could hurt it when you play sports or if you fall down. You might also get this problem from an activity that gives the area a regular pounding, like jogging.

Do you take uneven strides when you walk because one of your legs is longer than the other? That could be a cause of SI joint pain.

Sometimes, you start hurting when the ligaments that hold your SI joint together are damaged, which may make the joint move abnormally.

Arthritis can also lead to the problem. Arthritis that affects your spine, called ankylosing spondylitis, can damage the SI joint. You'll also hurt when the cartilage over the SI joint slowly wears away as you age.

SI joint pain may also start if you're pregnant. Your body releases hormones that cause your joints to loosen up and move more, which leads to changes in the way the joints move.
