I have read your query.
You should consult orthopaedic surgeon
. He will advise you some blood tests e.g serum RA factor, serum uric acid, E.S.R, C.R.P. He will also do your physical examination. .
After analysing all reports he would be able to tell you the root cause of your pain. You should also consult gynaecologist for hotflushes etc.
I hope you have got your answer.
