you should probably get her tested for arthritis, in the form of rheumatoid factor
, anti ccp and also get her thyroid profile.

who can check her out when she is having joint pains
to see for swollen joints.
as she was put on prednisone
earlier her symptoms are sure to subside, but if she is getting arthritis she needs to be on medicines called DMARDs.
