Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You have got pain in pelvis, groin, and hip area since very ling time. chiropractor told it is dislocation of the sacrum
. It was thought to be groin strain by the football team trainer.
As it is already 8 years passed, there could be little to do if there is dislocation. But i don't think it to be so. It may be a congenital displacement, or an arthritis
I advise you to consult an orthopedic surgeon for diagnosis and treatment. You may have to go for M.R.I. besides other routine tests for confirmation.
Wishing for a quick and complete recovery.
