Pain is the body’s alarm system. It’s designed to protect us from danger just like a home security system or a smoke detector. It’s the body’s normal response to acute tissue damage or injury and heals in normally 3-6 months.
But what happens when pain doesn’t go away?
Once pain persists beyond the normal healing time, it becomes chronic - losing its warning function and becomes its own disease/condition. It’s an abnormal response (with or without obvious pathology).
Although all pain hurts, not all pain indicates damage. We know what to expect from our pain by the very nature of it being chronic or ongoing. It’s not like getting burnt, twisting an ankle, or getting stung by a bee that needs protection until the injury has heals. Of course, any unexpected new pain should be investigated.
