Thank you everyone for your help with my other questions - I just have a few more to ask:-
1) I've been ill since 13 (I have Crohn's & lupus) and there will be TSH values going back to then would it help the endocrinologist to have a few old blood results? Never had T4 and T3 done before - having them measured next week?
2) should I take my temperature everyday in the morning for the next few weeks - am I right that this can indicate a hypothyroid?
3) my hair has gone really dry and I have suddenly got these white hairs that have started to appear out of nowhere in my normally jet black hair - could that be significant?
I can't wait for your input, many thanks and best wishes in advance,
