last year my ferritin level dropped to 5 and was put on ferrous sulphate 200mg 3 times daily, was on 50mcg levo (and still am) but my b12 was 1100plus. managed to get my ferritin up to 49 but coudn't tolerate the iron (have IBS as well) so GP advised stop iron and see what happens. Ferritin dropped steadily since then by ten points each three month blood test and now back down to 14 (tested last week) but surgery won't give iron as I am within normal range. blood last last time (3 months ago) showed tsh 0.84 and I felt fine but last 3-4 weeks sleeping all tme again with severe chest pains and breathing probs.
TSH gone up to 2.19 last week also, so guess I need more thyroxine now, but my b12 continues to be over 1000, should I be worried about this? I don't take b12 supplements, only adcal d3 in terms of vitamins.
