To all, I am taking b12 (usually hydro or cyano type) and I developed this pimples like cysts, they are huge and red and painful in chest, face and back area, I feel so good w the b12s but then I react (orally or shots). 1) Is this a reaction or a detox symptom? 2) Is there a way I Can prevent the skin reaction??? I ordered the active mb12 but have not received it, planning to start the b12 protocol but dreading the skin reaction. Pls advice.
