The most common microtrauma results in an extremely localized injury only to cells, the tiny muscle fibers, and the internal connective tissues. In this type of injury, the force is enough to damage cells but not enough to damage larger bundles. The body reacts on a microscopic level, with the immune system dispatching white blood cells to clean up the damage. Some mild and undetectable swelling or loss of movement may also occur.
These microtraumas are no different than the minor bumps or bruises you occasionally get on other parts of your body. The initial swelling and immobilization will temporarily inhibit movement and thereby reduce the production of normal nerve information. The reduced flow of normal nerve information allows newly stimulated pain signals to freely enter the spinal cord and brain and initiate a cycle of pain. Once the swelling has gone down and the area begins to move freely again, the pain quickly becomes blocked and diminished. These injuries usually require minimal treatment and resolve on their own in a few days without becoming chronic or debilitating.
