I suffered from SI pain for over 30 years. Early in my diagnosis I went to Cedars-Sinai Spine Center and after an MRI and consultation with 5 Doctors they told me my options were: surgery with 10% probability of success, injections, or take 3 Advil whenever there was pain (which was more than once per day) and wait until another option comes along due to advancing medical knowledge. I opted for Advil. I am now living near Mayo in Rochester and have pain-free for almost 1 year. My solution was a special plan prescribed by Mayo using a Mayo trained physical therapist to strengthen my core muscles (all sides, not just doing sit-ups), proper posture, hip placement, how to walk, how to sit, etc.The numbness in my legs and toes has also disappeared. I must be careful how I move and what I lift but that is a small price to pay.
