I have had a cough for about a month and a half now of and on. Recently I was diagnosed with B12 deficiency anemia with a reading of 209 and Vitamin D deficiency with a reading of 6. I have been feeling very fatigued for weeks. In fact, that is what lead me to the doctor's office for labs. The bottom of my feet hurt when I walk and I am physically and mentally worn out at work by noon. I am concrned about this. By the way, I have been on two abx, Augmentin, and Levaquin, along with a cortisone shot.
