This is my first post on this kind of forum, so I'm not exactly sure what to say, or even ask... When I was was 14 years old (I am now 20), I had a full thyroid removal surgery due to the gland being hyper and having many nodules and cysts in it. Since then I have been battling the constant highs and lows that come with being on what seems like every dose of synthroid out there. For the past two years though it seems like my levels just won't balance out; every 6 weeks I go in for a blood draw only to have my dosage changed yet again. I range anywhere from 112mg- which makes me feel absolutely horrible, to 137mg, which makes me feel like my chest will explode from my heart beating so fast. My endo, and primary physician are at a standstill and even though I go in for appointments every 6 weeks, they have no reason why my body won't 'balance out.' I can't handle these symptoms anymore, I constantly go from extreme highs to extreme lows (where I am at now), and I don't know what to do. Do I have to live like this for the rest of my life, or will my body eventually even out? Will I ever feel energetic and enthusiastic again? What happens if I just completely stop taking synthroid altogether?
