Hi all, just wanting to pick more knowledgeable brains than mine. First, a bit of history.
Hypothyroid for 40+ years and eventually diagnosed via Dr Peatfield and on NDT, but this became too expensive.
Moved to Levo 30 years ago (by then NHS was willing to acknowledge the problem as my bloods had entered their concern ranges.)
Perfectly happy then about 3 years ago I developed A Fib following a return of symptoms and Dr P suggested that I was unable to convert T4 due to RT3 and recommended I try T3. My GP at the time was happy with that and I've been on it ever since. Find it easy to manage and very helpful with occasional A Fib as I can adjust dosage easily if necessary.
Had an issue some months ago when the practice said they would no longer prescribe but CCG intervened, said I ought to see an endo and endo said I should be on it so I'm back on it.
Lately I have had a full blood screen because I've had some odd symptoms - some loss of feeling in left toe, slight numbness/pins and needles/sort of "pre-cramp" feelings in both calves, plus pins and needles around my lips. This last as eased slightly on a marginally higher dose but the leg issues persist.
This time I asked for B12 and ferritin too and these are the results with ranges (others available if needed):
serum ferritin (BSC) 62 ng/mL (10.00 -300.00)
B12 532 pg/mL (200-900)
serum calcium 2.33 mmmol/L (2.20-2.60)
I think what I'm asking is what the impact of these levels might be and what I ought to try to do about them (if anything). I am woefully uninformed about this kind of thing, so hoping one of you knows more! Surgery says all is normal and I have a consult coming up to discuss what next since symptoms persist - though they vary in intensity from day to day.
Over to you!
