My wife had surgery yesterday. The nurse asked her to rate her pain on a scale of 1-10. It immediately occurred to me that we have no better method than this highly subjective way to measure something so universal. Pain.
When pain gets to severe, a person goes into shock. Is that a 10? 10+?
What about the effects of pain medication? Is pain only what’s felt or is it an indication of trauma or damage?
What about animals? How do we quantify the severity of their pain?
Could we invent a tool to measure and quantify pain objectively? What would the unit of measurement be? What would such a tool look like? How would it work? How would it change the way pain is managed?
