GP has just called to say that urine tests have just come back showing urine infection, that I need antibiotics and that's what's been causing my tiredness. Had a scan this week where that doctor said had clear signs of thyroiditis - nodules, thyroid burnt out is what she said. But GP blood tests show TSH within range 1.2 (0.34-5.5), no FT4 this time, last time was 9.5 (7.5-19.0). Waiting for anti-body test results. Am on 25mg Levo based on set of tests with different doc in Nov TSH 4.21 (0.27-4.2) FT4 11.1 (12-22) Have a lot of signs of hypothyroid - excessive tiredness, weight gain, feeling cold, dry skin and still feeling dreadful. GP appt next week - what should I ask her to do now? Was thinking of asking her to test for FT3, B12, Irons, Vit D - anything else? will she think I'm a hypochondriac? How do I convince her that thyroid is at root of problem?
