Pain is a difficult thing to quantify or express. What’s considered painful to one person might not feel the same to another. When someone says they have a high pain threshold, what does that really mean? How do they know it’s higher than anyone else’s?
In 1971, Ronald Melzack and Warren Torgerson partnered to develop the McGill Pain Index, a self-questionnaire that allows patients to give their doctors a good description of the quality and intensity of the pain they’re experiencing. The goal was to better understand the level of pain for a wide range of conditions or injuries.
