My thyroid has been sluggish for years, but always just within the normal range, or with a raised TSH but still "normal" T4. I had a bad fall recently and my bloods were tested after that, my TSH was 23 (think maybe the shock of the fall had affected the levels? ). Had them done again last week and the TSH is down to 9.something , but this time they tested for antibodies and I do have them. I'm not seeing the doc for a couple of weeks which gives me time I suppose to work out what I need to ask. Has anyone tried natural thyroid extract? I had it three years ago when my TSH was raised , from a private doctor, but I felt terrible on it (sleepless, as though my heart was about to pack up) even though I was on a tiny dose. I feel generally grotty now and think I do need meds but am scared of how I might react to them. Not sure whether to try the Armour thyroid stuff again or levothyroxine. Is it normal to feel horrible at first on the medication, or should it be more of a feeling of returning to normal ?
