Muscle knots, also known as myofascial trigger points, are sensitive, hardened spots in the muscle that can cause pain and discomfort. They are typically found in the back, shoulders, and neck, and are often the result of muscle overuse, poor posture, or repetitive motion. These knots can be treated and prevented through various methods, including massage, heat and/or ice therapy, self-massage, stretching, and maintaining good posture. Muscle knots can be relieved at home, but if the pain persists, it is advisable to seek the advice of a healthcare professional, such as a physician or a physical therapist
