Doctor: I am very concerned with your low TSH level. Have you increased you medication?
Me: Yes by 25mcg (to 75 mcg) and I now feel well. All my symptoms have improved and don't want that taken away.
Doctor: I see what you are saying, but we are taught that the TSH level must be in range and yours is well below.
Me: But my FT4 is good and my FT3 is still at bottom of range.
Doctor: Your symptoms could get worse. You can continue on your current dose but you MUST have a blood test every 3 months so we can keep an eye on you. You could end up over medicated.
Me: I don't feel over medicated but yes, yes of course I will have regular blood tests! (under my breath "no way!")
Thank you all for your help and advice which gave me the confidence to stand up for myself and ensure that I don't suffer continuing symptoms unnecessarily through my doctor's ignorance.
