I have taken Levothyroxine for last 30 years. Originally 150 Mcgraw then recently downed to 125 and then 100
Was quite unwell when started but treatment seemed to work. Recently feeling unwell, nauseous, weight gain etc and have had various tests as they seemed to think thyroid ok. 2 weeks ago I had ultrasound scan on neck as worried about a lump wand was told my thyroid gland had totally atrophied. Waiting for follow ups and what hsppens next. Can anyone give me advice on this and what I should be doing now.
