I have been told I have a thyroid lump in the right lobe. I am awaiting an urgent USS and depending on the results whether it is a cyst or not, a biopsy also. My question is this. My TFTs have been normal and are normal now with the lump. I already have Sjogren's Syndrome, Fibromyalgia and Connective Tissue Disease. And my mother had hashimotos, and my two sisters hypothyroid. I would like to know if I can still have an underlying thyroid disorder such as hyper / hypothyroid / hashis even with normal TFTS, and that this is what could still be causing the lump. Also, even if hasn't affected my TFTS yet, if it is likely to do so in the future. Obviously I am very worried about the lump fullstop! But cannot understand why it has not affected my TFTS yet.
