Hi,

With such suvere pain it is often necessary to be examined by your GP.

IF there is some form of Neurological, or Orthopaedic issue, or even perhaps blood markers that can indicate what is happening, it is necessary to be referred to the appropriate diagnostics that will allow a plan to be formed regarding what is required for yourself.

If the above is ruled out, then appropriate referral to physiotherapy may be appropriate.

Regards
