Hi, my haemoglobin level dropped to 6.4 and I was given an iron infusion as I m unable to tolerate oral iron supplements. My haemoglobin is now 9.1 but I feel the same physically, achey limbs just from washing my hair and drying it, I have to stop several times to allow the ache to go, Short of breath walking short distances, cold hands and feet and a general feeling of exhaustion and light headedness. Is 9.1 still low? I was told my iron levels were low when it was 6.4. Regards Jemma
