I am a female, 27 years old. I have been going through alot of wierd things lately. I have been feeling weak and off balance feel as if I am shaking but am not really. My legs are the part of me that feels the weakest. My hands and feet are cold alot. I have been tested for thyroid problems due to absent period. Those came back good. I have been to the ER lots and all I get out of that is low magnesium which I now take a 400 mg supplement daily. I have re-ocurring sinus infections. I also have a low b 12 level which I take monthly injections. I am being told it's all in my head I have a panic disorder I am not taking that for an answer. I just want my life back so I can be a mother to my children.
