My hair has been thinning for about 2 years now and it was always brushed off as stress. No one ever did blood work until recently. My ferritin level was at 5 and my b12 was low. I have started weeklyb12 injections but all they have done for the ferritin is said that my hgb and hct is fine so don't worry about it. I don't feel right and haven't felt right in a long time. Something needs to be done or my hair is going to be gone and my sanity is going to be gone! I have almost pulled out in front of cars because my brain is in such a fog. It is horrible. I have already switched from my one primary who ignored my ferritin level to another in hopes she would do something and she did nothing as well. I am at a loss. Any suggestions?
