@iceblue - I have frequent pain in my SI joint. My daughter, a physical therapist. keeps encouraging me to follow an exercise regime. (I hate execise!) She also points out that I probably have PN stenosis scoliosis and sacral arthritis all at the same time, which makes diferential diagnosis and a treatment plan challenging! You might have a similar complex of conditions? And my chiropractor friend keeps reminding me that pain in say the foot is just as likely to reflect a back problem as it is a foot problem. In plain language we are statistically unlikely to get a comlete diagnosis or a complete treatment plan unless we are very lucky in our choice of Dr. or Specialist. I have tried injections, medical marijuana, chiropractic and accupuncture to no efect. Ibuprofen helps but The long term side effects are risky so I limit myself to 400 mg perhaps twice in a month. Mindfull meditation, weight control, cycling and a healthy diet have helped me to a) to reduce pain from say 8 to 4 on average...and b) to "accept" my condition with a consequent reduction in stress, anxiety, depression. ( previously depression and anxiety relating to my condition caused more problems than the physical conditions!)

Have a happy new year!
