I was diagnosed back in April after feeling exhausted and falling asleep all the time. I also had aching muscles and joint pains. Not to mention brain fog! I was told my thyroid levels were "a bit low" and that "there are some antibodies". I was prescribed 50mg Levothyroxine and told to get my bloods checked after 3 months. Phoned for results and was told "everything normal" by a receptionist. Had another blood test last week (3 months) When I walked into the phlebo room she asked what I was having done. Stupidly I said Thyroid levels and that's what they tested for. TSH only! It has gone up from 1.8 to 3.6 and is within the range. Afterwards I wondered if I could have asked for everything! After reading a lot of stories on this excellent forum I have realised that it is DIY ! I have been gluten free for the last 9 weeks and a couple of days ago I ate a mince pie as it was offered and I ate it without thinking! Big mistake! I had joint pains and a peculiar lump in my throat feeling, like I was going to get a sore throat. Would the gluten have acted that quickly? Also have had a weight gain of 21 lbs since starting thyroxine. I have always had a slow pulse rate about 55-60 is normal for me with a low blood pressure. Always told I am healthy! Clearly not! Any ideas what I should do/ask for ??
