One thing I really cannot understand is pain. I’m not ralking about acute pain, but chronic pain. I don’t get it. I see no purpose or value for someone to feel constant pain without a reason associated with it. An example that comes to mind are migraines. Extraordinarily debilitating headaches that medical science has yet to explain very well. The pain one experiences is extreme. My question is why. I understand pain is a warning to our brain that something bad is going on with our bodies. I can imagine early humans breaking an arm. If they didn’t experience that acute pain they wouldn’t know something is wrong and may end up with a completely useless limb. In turn that persons chances of survival would be greatly diminished. It would be difficult to hunt wit one arm. Pain is definitely necessary when it comes to survival. It is distressing when pain becomes something that never seems to end and has no known purpose. It’s extraordinarily frustrating and stressful.
