Any help much appreciated. I’m over a year PP first baby 23 female. I’ve not felt well now for months had endless tests and seems to be low ferritin everytime I’m now on tablets but my b12 also 288 so think it’s lower end. I’ve had the worst panic attacks to the point I can’t even go out, I have never had anything like this in my life. I’m so tired I feel weak most days breathless etc. can a deficiency make you feel this awful I’m absolutely fed up! My ferritin level is 24 which has gone up from 11.
