6. Muscle Microtrauma

In contrast to an abrupt muscle tear or strain, “microtrauma” refers to very slight muscle damage that can come from hypoxia, prolonged muscle spasm, local muscle abnormalities, or ischemia (restricted blood supply to the tissues). This can develop from an injury, but is more likely to come from a muscle imbalance: problems with circulation cause a drop in pH and muscle enzymes to stop functioning properly, which depletes energy and can lead to these tiny structural changes that interrupt normal function. Some studies have found evidence of microtrauma in muscle biopsies of fibro patients, which could help to explain the deep muscle pain.
