I was diagnosed hypothyroid 4 years ago. A year ago my TFTs revealed normal T4 & TSH on Eltroxin 75mg daily. However, my blood test also revealed a low (abnormal out of range) TOTAL T3 - (free T3 not available). My endocrinologist completely dismissed it as meaningless and said it shouldn't have been ordered. She referred me to a rheumatologist for my ongoing muscle pains and spasms that have been getting progressively worse - I was seen by the rheumatologist who told me he 'suspects it is my thyroid' as he says muscle/joint pains are common in people with hypothyroidism even when optimised on Eltroxin.
My question is does LOW TOTAL T3 automatically imply LOW FREE T3?
I have searched forum and internet and all I can find is the insignificance of a NORMAL Total T3 - I can find nothing regarding significance or otherwise of a LOW TOTAL T3 in the context of HYPOthyroidism.
Thanks in advance
