The past week I have really being feeling awful, my hair is thinning out rapidly, my breathing is laboured, my chest feels tight, their is a thick white covering over my tongue, a bitter taste in my mouth, lots of stomach aches, along with all the normal symptoms, I have barely had a winks sleep in the last week and I just feel dreadful but I haven't changed my routine at all - so why am I feeling worse. I take a quarter of a tablet of Thyroid medication every 5 days (all I can tolerate) and have a lorry load of vitamins a day. I have spoken to the GP but get a blank expression and told to speak with the endo - she said they won't test for any other illness until the Thyroid is better because the Thyroid is the cause of most things. What can I do to feel a bit better - I can't stand feeling like this, it's made worse by the fact I do not know what to do to improve things, or why things have changed dramatically. My test results are all ok except the TSH and low cortisone - so that doesn't explain why feel like this.
