Had this happen to me for the first time today. Three jalapeño peppers and my fingers/hands were burning for six hours (starting about an hour after I finished mincing). I usually wear disposable gloves but didn't have any in the house. After a lot of reading online, I saw a post regarding Vaseline having given fairly instant relief ... I tried Aquaphor and it worked great! In less than ten minutes the burning sensation diminished significantly and it continued to abate further after that.
