Muscle knots, also known as trigger points, are tight bands of muscle that can form in any muscle group. They are often painful and can cause difficulty moving the affected area. There are many different ways to alleviate muscle knots, including massage, heat therapy, and stretching.
Muscle knots can be caused by a variety of factors, including overuse, injury, and poor posture. They can be a nuisance or they can be debilitating, depending on their severity. In some cases, muscle knots can lead to other health problems, such as headaches, neck pain, and back pain.
