Myofascial pain syndrome (MPS) is a common musculoskeletal disorder characterized by localized or regional pain originating from myofascial trigger points. These trigger points are hyperirritable spots in skeletal muscle fibers and their surrounding connective tissue (fascia) that can cause pain, tenderness, and dysfunction both locally and referred to other areas of the body.

Causes of myofascial pain syndrome can vary and may include:

1. Muscle overuse or injury: Repetitive movements, poor posture, or sudden trauma can lead to the development of trigger points within muscles.

2. Muscle tension or stress: Psychological stress, anxiety, or emotional tension can contribute to muscle tension and the formation of trigger points.

3. Structural abnormalities: Imbalances in muscle length or strength, joint dysfunction, or spinal misalignment can create abnormal stresses on muscles, leading to trigger point formation.

4. Systemic conditions: Certain medical conditions, such as fibromyalgia, chronic fatigue syndrome, or autoimmune diseases, may predispose individuals to develop myofascial pain syndrom
