I have been experiencing extreme fatigue in the past three

Customer Question

I have been experiencing extreme fatigue in the past three months. I have had some dizziness off and on. I have vitamin b12 shots every two weeks, and it is not helping me. I was wondering if you think that I may need a full blood panel done. My doctor has had that done before about a year ago, but I am feeling much worse now. No energy at ALL.
