Most pain starts when part of the body is hurt. The pain or discomfort is caused by messages sent to the brain, which travels along the nerve as electrical impulses. Those messages tell the brain that the body is being damaged. The message that the nerve sends to the brain is called nociception.

Pain is not just the message the nerve sends to the brain. It is the bad emotion felt because of that damage.

Hippocrates believed that pain was due to an imbalance in vital fluids.

Giving birth is the second most painful thing a human can experience – The first is being burned alive.

Pain travels through our bodies at a very speedy 170 miles per second.

Rubbing an injury right after it happens alleviates pain because the spinal chord preferentially forwards pressure signals to the brain over pain signals.

Americans consume 80% of the world's painkillers.
