Headaches and migraines trigger more suffering than pain in any other part of the body, new research has revealed.
Scientists claim that discomfort will always feel worse in the head – regardless of if someone is struck at the same force and impact on the knee, arm or anywhere else.
They discovered a previously unknown network of nerves that sends pain signals from our heads directly to the part of the brain that deals with emotion.
The findings may help to explain why headaches are considered to be one of the most unpleasant forms of pain, researchers said.
Scientists from Duke University said that until now it was unknown why people rate pain as worse when it affects our heads.
