Broke my big toe 6 weeks ago tripping over.Have been going twice a week to the surgery to have it dressed because of a small cut,( having Diabetes didn't want complications) in between the 1-2 toes.Went to a foot Podiatry on Mon said everything was fine but as a precaution she asked me if I was allergic to Iodine.I said I don't think so ,So she put a small Iodine plaster on it.After all these years of modern medicine they still use IODINE
