Explain Pain Section 3: The Damaged and Deconditioned Body

This is a summary of section 2 of “Explain Pain” by David Butler and Lorimer Moseley. Tissue Injury 101 When a body is damaged, pain is often the best guide to promote optimal healing. Sometimes it is good for us to rest, other times it is better to move. A similar healing process occurs for all tissue injuries. First, inflammation floods the injured area with immune and rebuilding cells. This reason is why inflammation is a good thing in early injury stages. A scar forms once the inflammatory process is over. The tissue then remodels to attempt to become as good as the original. Blood supply and tissue requirements determine how fast the healing process occurs. For example, ligaments heal much slower than skin because the former has a lower blood supply than the latter. This may also be a reason why aerobic exercise may speed up the healing process. If present, pain usually diminishes as the tissues heal. However, pain may persist if the nervous system still feels under threat. Acid and Inflammation The alarm sensors described here constantly work and often get us to move. Movement keeps our system flushed. When we don’t move or a physical obstruction is present (e.g. sitting), acid and by-products build up in the body tissues. Oftentimes we will start to feel aches and pains when we stay in a prolonged position, which is our body’s way of saying “get up and move.” Much like the alarm system, inflammation is a primitive way for our
