I went to see a private endo yesterday recommended by someone on here. It was a very helpful visit with numerous ways forward to get rid of my worst symptoms, the muscle aches and complete lethargy.
She checked my private tests and the first step is to raise my ferritin level to over 70. It is currently 13. I now have to get iron sulphate tablets and start on those. She is quite confident this will help greatly but is happy to try other things if it doesn't, which is good.
As someone with little knowledge of thyroid conditions, it was interesting how she explained Hashis. She said that I have very angry antibodies which have decided to attack my thyroid. At some point they may decide to attack other things so I need to bear that in mind in later in life.
She is going to ask my doctor to check for lupus and coeliac and arthritis and get me a booster shot of Vit D as the 1000iu I am taking is not enough for my low levels.
I definitely recommend getting the tests done privately if you have to. It means that I've spent the holiday money for this year, but I wouldn't have been able to go on one anyway as I have felt so bad.
