Hi, I've recently diagnosed with hypothyroidism. I've been taking levothyroxine 0.05 mg for a little over a month now. I immediately noticed improvements. My tierdness faded, and I felt more energetic overall. However, for the past three days, I began to notice the same symptoms I had before taking the medication. I feel tired, and there is a funny slightly choking feeling in my throat. I just took a two hour nap and I'm still tired. Should I be concerned about this?
