Received my blood test results yesterday and was told 'All normal'. I asked for the figures and was told TSH 0.74 and B12 240. I am on 125 mgs of Levothyroxine. About 8 months ago I was given B12 injections as I was considered deficient. I'm feeling tired and achy again and I'm disappointed that I'm not getting more at the moment. I am 71 and have only one kidney after cancer 4 years ago, my adrenal gland was removed too. The cancer hadn't gone into the lymph system and six monthly scans have so far been positive. I have never seen an endo, just my GP and wonder if I should ask to be referred.
