Hi all, I went to discuss my latest blood results with my Doctor a few days ago. My latest ferritin was 28. This was taken about 6 weeks ago.However as it is not below 17,she said she could not prescribe me iron meds. Been awful last few weeks,tired,achy,tingly hands and feet,palpitations and hair is falling out. She said its prob anxiety and she gave me a printout sheet about Raynauds when I mentioned tingly sensations. However she said I can buy ferrous sulphate over the counter which I did. Can anyone give me advice on how many I should take a day? Currently just taking one but I know you can take up to three. Don't think 3 may be ideal as not anemic.what do you think?
