My husband woke up with a black eye a few days ago. I thought it was because he ate candy that had sulfur in it we didn t read the label he is allergic to sulfur but it as been 3 days now and it is no better. I have been giving him benedryl I can t help but wonder if it is something else that cause this, how long does sulfer stay in the body, he did eat allot of the candy and did get the rash after that and then I looked at a label. OUr friend gave us the candy she brought back with her from Italy.
