Fatigue and weakness, insomnia, cold intolerance and weight gain are some symptoms of hypothyroidism. Surprisingly, I am experiencing these symptoms as well. I have a feeling I have thyroid imbalance but can't confirmed it yet since I haven't had myself take a test. Perhpas if my instinct is right I may be prescribed to take a hypothyroid treatment austin. People have been asking me if I have a goiter, but no one cares if I'm hypo. lol.
