Orthopedics Questions? Ask an Orthopedist for Answers ASAP
I am an Orthopaedic surgeon and I would be happy to help you today.
I have read your question carefully.
One of the possible causes which probably might not have been ruled out would be a disorder of sacro iliac joint.
A scintigram would be able to show any inflammatory changes in the sacroiliac joint and may help to diagnose.
I would also suggest that you see a Rheumatologist as pain specialist and Orthopaedic specialist have not been able to find anything significant in the way of Pathology.A rheumatologic underlying disorder should be ruled out as well.
Feel free to ask any follow-up questions .
