Allergy to prescribed 400 mg of B2 riboflavin?
I was newly diagnosed with small fiber poly neuropathy. My neurologist put me on 400 mg of vitamin B2 in addition to 400 mg of magnesium. About two weeks later, I experienced what felt like being electrocuted from my toes to my pelvis with extreme itching including both arms and needles in my torso. All day long. At first, I thought it was an extreme exacerbation of the polyneuropathy, but then I stopped the riboflavin as I wondered if it was an allergic response. The electrocution stopped after two days of stopping B2. Has anyone else had an allergic response to riboflavin or magnesium, and what did you do about treating your poly neuropathy?
