In the US, about 50 million people have some form of chronic pain, yet there is little known about how and why we feel pain. (Although the revelation that chronic pain may be caused by healthy nerves, not damaged ones as previously though, may change that.)
FOX News examines chronic pain in The Pain Truth: How and Why We Hurt. From describing how little is known about pain to the complexity of it to ways to treat it, the article teaches the basics of pain.
According to FOX, researchers at the Mayo Clinic say “chronic pain, which might result from inflammation, can be amplified and distorted like music turned up beyond a speaker’s capability, causing pain out of proportion to the source.”
