Hi all, I am fairly new to this. It started just after the Easter weekend (end of March 2013). I had good and bad days at the start for the first couple of weeks and even had a couple of completely T-free days but when I woke up the following day it was back with a vengeance and gave me a great sense of disappointment and made me feel very low indeed. I am now in my 3rd week and it has remained pretty much constant (high-pitched whistling and hissing mainly in left ear). I have just had some bloodtests for Thyroid hormone levels and the results are due back in about 4 days. If they are inconclusive my GP says she will refer me (not sure where). Anyway, I will be happy to read all your posts and respond if I feel I can be of any help or have any questions. Many thanks, Sybs.
