I have just started take 25mcg of Thyroxine, recently had thyroidectomy (apparently some tissue left and still working). I have awful reflux and chest pains. I know it’s the thyroxine because I stopped it for 3 days and didn’t get pain. My Endo said keep going for 2 weeks and see if it improves. I’m really struggling, lansoprazole and gaviscon not helping at all. Anyone experience this? I’m so miserable, eating plain foods and tiny portions.
