When you are injured the degree of pain is not proportional to the degree of damage. There are more variables that are involved than tissue damage. The body, brain, interprets how dangerous the situation is. It looks at the present situation (ie, physical, emotional, environmental, psychological variable), past injury situations, and it looks at the future consequences of the injury. It evaluates the situation and then outputs what degree of threat it is.
One person may stub their toe and just keep on going. Another person, who had previously broken their toe, may be writhing in pain.
For some, they may tend towards anxiety, depression, or they may catastrophize the situation. This increases the danger and thus more pain will be experienced. A draw back to this is that these “Danger in Me” thoughts cause people to avoid what they need to do. This slows their progress in rehab, reducing their enjoyment and quality of life.
My job, with my athletes, is to reduce the anxieties or worries of their pain. Also, I am to help put themselves in situations where they can work the injured area in a “Safe in Me” environment. Building themselves up to the point where they can enjoy their sport, activity or life again.
