Today I was making a phone call and had only a little bit of stress while asking some questions, and somehow this translated into a sudden reaction of very red and burning ears, red spots on my forehead, reddening of the face, as well as itchy red skin on the upper part of my hands and arms. I also felt a sudden stomach or intestinal discomfort. This lasted for about five minutes. Another symptom I noticed yesterday was a slight numbness of my head, specially to the back. I did take more L-Methylfolate a couple of minutes before this, from 400 to 800 mcg as it was suggested for a decrease in depression. The actual suggested amount was 10-15 mg per day thou.
