I have taking 200mc of thyroxine for around 3 years, I also have phsoritic arthritis and fibromyalgia. So it's difficult for doctors to diagnose when I'm feeling ill, which is majority of the time. I have my bloods taken every month, however it is only to check my arthritis medication, every time I disscus my medication with doctors and consultants when I tell them what my dose is of thyroxine they always comment on it been a high dose. I only have my thyroid checked yearly, even though I still feel unwell, when it is checked they say my levels within range. When I read about others regarding not been given the correct testings this worries me, as even though I was diagnosed in 2007 I was only told vey little, like one level was to high and the other to low. I am going for my bloods to be taking next week, I am going to ask to have my thyroid to be tested to. Is there anything I need to ask nurse to check, also what do I need to ask my gp when I go for results, I'd be grateful for any advice as I'm fed up feeling ill all the time.
