Hello, I read your message and understood your medical issue. Before I run my final conclusions I would like you to send to me or the medical test papers you may have done till now. If you can please send photos to me. Of course, anemia may cause these symptoms (dizziness, weakness, cold hand and feet, numbness of hands and headaches). But there are many other conditions and diseases that must be taken into account. I think you must see your doctor as you need further evaluation of your general health. A neurological physical examination must be done to see if there is any trouble with nerves and the neurological functions. If the neurological examination reveals troubles other examinations will be ordered such as a head CT scan for example. The blood tests must be repeated in order to determine if it is anemia for sure, what type of anemia it is and how it can be best treated. You must check blood sugar levels too and the function of the thyroid gland. Hypoglycemia and hypothyroidism may cause such symptoms too. It may look something not serious but it can turn to be serious. Hope this is helpful for you. Dr.Albana
