Vitamin Deficiency?

Hello everyone, I have a problem...I have had my labs check many times and they come back normal, I had my thyroid check,neck x-rayed, and a ultrasound of my neck & thyroid and everything is fine....my problem is that my hair is falling out badly and I am getting these dark spots on my legs and feet. My doctors recommend that I go to a dermatologist...but my insurance doesnt pay for one. Daily I take 2 multi-vitamins, 2 calcuim caltrate w vitamin d, and weekly b-12 shots,1 5mg of biotin do anyone know where I am going wrong? if I am going wrong?Like I said before my labs are fine. could this just be something that is unrelated to wls? Any information would be a tremendous help.

If you have ER coverage, then go there to get those spots checked on your legs.
