The Justin O. Schmidt Pain Index is a pain scale rating the relative pain caused by different kinds of stings. Like the Scoville scale, which measures the heat index of chili peppers, the Schmidt Pain Index increases as the pain does. His descriptions are rather like trying to define the various flavours in a glass of wine, and bring horrific imagery to the index.
