The Chiropractor Says That I Have SI Joint Hypermobility. I

The chiropractor says that I have SI joint hypermobility. I have chronic soreness and tightness in my si joint area. I workout a lot and have tried yoga, Pilates, massage, adjustments,every kind of stretch and si joint strengthen exercises,but nothing seems to work. I get mild relief,but I can barely bend over with out serious pain. This has been going on for almost a year. Do you have any suggestions and will a teeter inversion hang up help. Thanks angie
