I nearly passed out in a meeting at work two weeks ago. I went to the GP and had a blood test, which showed my ferritin is 6, but my blood count is normal.
I feel terrible. I'm absolutely exhausted. I can't concentrate on anything. I have a permanent headache. I'm dizzy and I get palpitations and feel short of breath just walking up my own stairs. I'm having crazy mood swings. My hands and feet are freezing cold.
All classic anaemia symptoms AFAIK, but GP says I'm not anaemic (because blood count okay) so it's not that. They've prescribed iron tablets but only one a day and they're not doing follow-up blood tests to see if they're bringing the ferritin up. (I've actually been taking two a day, but they don't seem to be making much difference.) They just say my ferritin's a bit low, but it's really common in women 
What can I do? I've already had a week off work, and I've been working from home all week this week, but I've barely got anything done because I feel like I'm in a fog. I'm trying to up iron in my diet, take the iron pills with fruit juice, don't drink tea or coffee.
Has this happened to anyone else? How long did it take to feel normal again?
