Could someone please list the definitive tests I should ask for from my GP? I have had hypothyroidism for 25 years and my dose of thyroxine has been between 125, 200 and most recently 150mg of Eltroxin (until it's withdrawal, then Mercury Pharma) since my referral to an endocrinologist 3 years ago when my TSH was at 34.8 (I have no other readings from this time other than this) I am in the process of being referred to a rheumatologist as I have been suffering with calcific tendonitis of both shoulders and now the Achilles' tendon. When my blood test came back last week it gave thyroid readings of TSH <0.01 L mU\L (0.35-4.94) and Free T4 17.1 pmol/L (9.00 - 19.0) no other thyroid tests. I have also previously had repeated blood tests for high creatinine levels but to my shame I don't know why. I feel rubbish, mainly aching, sleep problems, go off OK but wake 2:00 then can't get back off till it's almost time to get up. No libido and I mean none, and since June I have put on over 1/2 a stone in weight despite no extra food intake? What is happening? I would be so grateful for any ideas! I am a 55 year old female.
