In 2010 I had 3 surgeries within 9 weeks, which I was told could have been a factor in me having thyroiditis. Even though my consultant suggested I may need thyroxine the GP's I have seen since do my bloods and tell me my results are normal. When questioned they have all said I am on ' the lower side of normal'. I am 56 years old and most days I need to nap I am so tired and lethargic as well as having other classic symptoms. On a recent medication review for the Sertraline I take, I saw a different doctor, and I again questioned my thyroid and T4 results. Again I was told I am on the lower side of normal and I explained I feel my memory is poor and my tiredness. She offered me a trial of levothyroxine 25mcg for 28 days and then to have a blood test 6 weeks later. After reading and researching I am now wondering if taking this dose for such a short period will do anything for me at all?
