Muscles account for over 60% of human body mass and are responsible for all body movement. They are susceptible to injury from overuse or repetitive strain. Muscles can involuntarily contract in small portions, known as trigger points, which cause localized pain and dysfunction. Trigger points are a common cause of musculoskeletal pain and can refer pain to other body areas. Applying moderate to heavy pressure directly to trigger points can help relax the muscle and reduce pain. Self-treatment of trigger points using tools like the Pressure Pointer can provide effective long-term pain relief without costly professional treatments.
