I had a bout of Hives about 4 weeks ago, never had it before. My GP suggested a blood test to see if there was an underlying problem. I was called in last week to be told my T4 T3 (not a clue what they are talking about) was okay, but that they had also tested me for anti bodies and this had come back high (from memory 52?) and therefore I was being put on levothyroxine 50mg to start but he expected it would increase in dosage. He also checked my neck and said it was swollen (something I had thought myself, but thought it was an age thing). I have had no symptoms to speak of, so it is all a bit of a shock to be told I will be on medication for the rest of my life. He said I had autoimmune disease (is this the same as Hashimoto disease?) Reading the forum has confused me even more,gluten diets/should I still be using my treadmill? I realise i should have asked him to explain more, and when I go back in 2 months time I will, but in the meantime any help much appreciated.
