<<Disclaimer: Verify this information before applying it to your situation.>> Hello, My husband has been on a GF diet for over two years and we follow it strictly. We discovered recently that he was very deficient in Vitamins D and B12. His doctor prescribed injections which he has been taking religiously for the past 8 weeks. About 4 weeks ago he developed a burning sensation in his feet and hands (especially in his feet), also known as a neuropathy. He is not diabetic nor has any other reason for these symptoms. The pharmaceutical companies who manufacture the Vitamin supplements he injects are adamant that it is not a side effect. Also, my husband experiences intermittent abdominal pain, bloating, burning, while his gut seems not to be working and his appetite absent. After about 48 - 72 hours hyperactivity in the gut sets in with an increase in appetite. These episodes appear about every 3 weeks WITHOUT EXPOSURE TO GLUTEN Whatsoever!. I would appreciate any input from fellow celiacs on both questions and also any suggestions for further research. Thanks in advance. Uli Johnston Eugene, Oregon
