My wife suffers from Polymyalgia (or so the doctors/consultants say). Her ESR and CPR levels indicated this is what she has and is being treated for with Prednisone. However, 18 months on and she still suffers. I have just been diagnosed for under-active thyroid and looked her results. Her TSH level was very high at 8.09 but free T4 15.8 and "normal". Also her peroxidase antibody level was 247 and I understand it should be <50! Looking at the under active thyroid symptoms she has sensitivity to cold, muscle/joint aches and pains & tiredness. Anyone out there been diagnosed with Polymyalgia and it turned out to be thyroid issue or maybe my wife has two issues?
