Hello, I have been reading varoius posts for sum time now. I was just recently diagnosed with hypothyroid. I'm 28 years old and very active in bodybuilding. My TSH level was at 8.24 I'm not sure if that is really high or not. All I know is I was feeling horrible tired all the TIME, Very cold, puffy eyes, VERY BAD ANXIETY is this normal? as well as loss of hair, yellowish skin, brittle ugly nails. The doctor put me on synthroid .5mg, it has been 5 days.
