C.C.
A lot of women over twenty-five have thyroid problems. Either Hyper-overworked or Hypo-doesnt work. I have Hypothyroidism. My symptoms were, being tired all the time, crying spells even when I wasnt sad, some depression, and then it started makeing me have chest pains, and digestion problems, plus weight gain. My friend had Hyperthyroidism and she was just the opposite, she didnt hardly sleep, going all the time, ate like a horse and never gained an ounce.\
Just because the levels came back normal doesn't mean anything, have him run a full thyroid panel including a t-cell count. A simple blood test doesnt always show.
Good luck!
