injury moment
Take another look at the graph below. Injured tissues
have reasonably defined healing times. However, healing
timesmay vary because of associated disease processes,
how the tissue is used, and the things that people do in
life. Reflect on the amazing pain stories and a key point
from that section – that damage and healing does not
necessarily relate to pain. We know that pain persists in
many cases even though the initial injury has had time
to heal.
In these situations, the brain concludes that a threat
remains and that you need all the protection you can
get. There aremany explanations for why this occurs.
Many of them involve changes in the way the alarm
system itself works. We’ve covered the changes that
occur in the periphery in the last section. Changes also
happen in the spinal cord and brain.
