Hey all, sorry to keep asking but am trying to get my head around the info available to put my case to my gp on Monday. From what I have read and from my results (posted on Wednesday) I think my problem is converting t4 to t3. My b12 and feritin are also at the bottom of the range which may be contributing to this problem. My hb is good (14 gdl) so no anaemia as such, more a problem of converting again. If my gp is still saying there is nothing wrong with me should I be asking for b12 injections and a trial of thyroxine or just b12.? Or should I ask for b12 and t3 meds.? I find it amazingly wants to prescribe a trial of anti depressants to help me but no trial of thyroid meds! I was down last year as a close family member died of cancer but I had already seen my gp in 2008, 2010 and 2011 with this long list of symptoms. So just trying to get straight in my mind what I should be asking for?
