I have a pretty rare condition called chilblains. I've been on a plant based diet for almost 13 years and I've not been able to find relief or anything resembling treatment. Chilblains are these red itchy sores that people get in the winter (usually on hands and feet). I've recently started taking a niacin supplement to help with blood flow and it may be helping a bit. Curious to see if there is anybody else that has this condition and to see if they've found anything that helps.
