why do we get pain in our body
Answers
Everyone has felt the ache of a stubbed toe, the twinge of a pulled muscle, or the throbbing of a bad headache — but do you know why? The pain response we take for granted is actually a sophisticated and instantaneous chain reaction.
Pain happens for one simple reason: to protect you. If your brain registers pain, you typically stop doing what caused it. It goes back to the "fight or flight" instinct. Pain is the body's way of letting you know that what you are doing is harmful, and that you need to stop.
Pain starts at the source of an injury or inflammation, whether it's your toe or your lower back. When you injure yourself, the body's automatic response is to stimulate pain receptors, which in turn release chemicals. These chemicals, carrying the message “Ouch, that hurts,” go directly to the spinal cord. The spinal cord carries the pain message from its receptors all the way up to the brain, where it is received by the thalamus and sent to the cerebral cortex, the part of the brain that processes the message.
