Hi, I have an underactive thyroid for quite a few years now but I am still feeling extreme fatigue memory problems, muscle aches and weight gain. I am taking 150mg eltroxin one day then 125 mg the next. My last results said my tsh level was 6.63 but yet they say it is within *normal* range and that I do not need my meds increased, is this right? I thought I would need to be at around 3.0 or just above to be in the right range. I am so fed up of feeling unwell I am going back to my doctors today to tell her I want my meds increased as I am still having symptoms but I know I am going to have a battle on my hands... I persuaded my gp to refer me to an endo some months back as my hypothyroidism has not been under control for about 5 years and Im so fed up of feeling they way I do. Gp told me the wait list would be long due to the fact the endo has to see really sick people and I am not in other words! Do I need to be asking her to test my T3 ad T4 ? Any help or advice would be so helpful thanks.
