Good Morning, Please tell me what to do after reading so many articles on Vitamin B12 def., I believe this may be my problem. I have so many of the symptoms. I have the white spots that suddenly appeared on my body, always fatigued, burning, itching and pain in legs and some numbness every now and then. I get this coldness that goes through my body. I also have this burning sensation on the side of my breast. My elbow hurts like crazy, and I also experience tingling.
