Hi everyone, I am an RN & my speciality has always been Hemodialysis. I am no longer able to work, ( I've have had 3 back surguries). I had some blood work done and my T4 Free is low, but my TSH is ok. I've heard conflicting opinions about this. Some say that the T4 Free is more important, others say the TSH is more valueable. I do have sx, but they are vague and could be attributed to other things. My sx are weight gain, I have really dry skin, low energy. I have dieted and exercised and have not been able to lose the weight. I would be grateful for any current info.
