I have many symptoms that point to hypothyroidism, dry skin, thinning hair, insomia, low body temp, low energy levels and weight gain. My TSH was 3.47 which according to my Dr. was within normal range as was my free T4. However I have read on several different websites that endocrinologists now consider TSH readings over 3 to be hypothyroid. I have brought this to my Dr's attention but he says that normals vary from lab to lab-depending on the type of test performed? I just want to feel better.
