I am 37 and Doc says I don't have hypothyroidism, yet I have a lot of symptoms and my TSH is getting into the high range of normal. also Free T4 is .8 as of last year. I'm in the middle of switching docs and my appt is about 3 weeks away. My symptoms consist of fatigue, scalloped tongue, heart palpitations, joint pain, brain fog and the list goes on and on. Also, my mom, both grandmas, and great grandma had hypothyroidism and a cousin has Hashimoto's Thyroiditis. My mom also has other auto immune diseases. Anyone out there with a little insight that may have some input would be greatly appreciated! Thanks
