I remember you.
I am glad you requit the smoking. Hypothyroidism will cause all the issues you mention. Make sure that you get tested for Hashimoto's thyroiditis in conjunction with another TSH and Free T's if at all possible. The MDs will know what you are talking about if you ask for the tests. Whether or not he will run Free Ts or Total Ts will depend on him and his idea of care required.
Apple, Mad Maz, pursie, and many other english ladies roam this board and may be able to answer some more specific NHS of UK questions. It is hard for us to understand your system, but we do understand how hard it is to get optimal care.
I wish I could help you out more and I wish the MD didn't wait so long to get this next round of testing done. By law the MD has to release a copy your labs to you is you ask. This holds for your UK health system as well as our US health care system.
Ask the ladies at the front desk.. don't bother the MD with it. It is beneath their responsibilities.
Yes, one MD told me that. He got my you are so full of it smile.
