Ali Mesiwala, MD, is a California-based neurosurgeon who heads the neurological surgery department at St. Bernardine Medical Center.

A board-certified physician, Ali Mesiwala, MD, is also engaged in several professional associations, including the SI Joint Society, of which he is a founding member.
The SI Joint Society is a professional association of surgeons who diagnose and perform surgery related to the SI joint. “SI joint” is the shorthand term for the sacroiliac joint, which is located below the lumbar spine and above the tailbone, connecting the sacrum with the pelvis. The primary role of the joint is to carry the weight of the upper body when a person is upright.
Although there are many factors that can lead to SI joint pain, it typically results from either too much or too little movement. Too much movement, known as hypermobility, causes pain to be felt in the lower back, hips, and groin. Too little movement in the joint, or hypomobility, causes pain to be felt in the lower back, in the buttocks, and down the leg.
