Pain is useful – indeed, this is an old theory to which British scientists are turning again. They argue that if something hurts us we should not immediately rush to the pharmacy and let pain do its job.
Pain is a signal of danger, like a body alarm that something is wrong – kind of a warning for stem cells to target the affected area and to solve the problem.
Pain for 40 years is considered a hindrance to the healing process and pharmaceutical companies created all sorts of ways to blunt her not so things were two centuries ago. Then educated in medicine believed that pain is part of the healing process and even more were doing operations without anesthesia, as barbaric as it sounds, there may be some logic in this.
Studies show that if, before heart attack, a person experience chest pain, the chance to save much more than if you do not feel alarm.
If you block the pain with drugs that prevent the stem cells receive the signal of danger, which is sent from the brain and recovery of damaged tissue is difficult. The feeling of pain is not only way our bodies warn us that there is a problem, but he struggles with the problem.
Pain is produced by the brain, rather than passively perceived by the brain as feeling that comes from the body. When a body part is damaged, the nerve endings send signals to the brain, containing information about the nature of the damage. But pain can be felt before the brain interprets this information and decide that the pain would be a good way to prompt you to take action that will prevent and heal damage. Brain reported a large amount of factors when making its decision and no two human brains, which will take the same decision. Many parts of the brain help in the response of pain, including areas that control emotions, past memories and future problems.
