You have pain that wakes you up at night and distracts you during the day. You go to the doctor, who asks you to grade your pain on a scale of 1-10. The doctor can't find anything wrong with you; it may be stress or anxiety or that you need more exercise or sleep. You're confused. You feel pain but nothing seems to be wrong. Does this sound familiar?
The CDC reports that almost twenty percent of adults in America live with chronic pain that's severe enough to interfere with their life and work. Chronic pain is the kind of pain that lingers after an injury has healed or exists in the absence of injury, like that back pain that keeps you up at night.
Pain is a subjective thing that is shaped by culture, environment and genetics. Doctors have limited ways to understand the pain of another beyond asking one to grade its intensity on a scale from one to ten or find a word that best describes it. Often, if a doctor can't diagnose a specific cause for pain, they don't understand how it can exist.
Yet, it does exist and researchers are trying to prove it by scanning the brains of thousands of people, healthy and sick, to find a neural and objective map of pain: how the brain reliably creates perceptions of pain.
Also this hour: "Man on Fire Syndrome" results in severe pain and sensitivity on skin, hands, and feet. A Yale researcher studies this rare disease to find new treatments for chronic pain.
Lastly, do fish feel pain? If so, should we adopt laws requiring the more humane killing of fish? Also, why is it so hard for us humans to accept that other species have the capacity to be feeling and conscious beings?
