Myofascial trigger points refer to localized areas of hypersensitivity, commonly found within skeletal muscles and their surrounding connective tissue called fascia. These points are characterized by the presence of a taut band of muscle fibers, which may be palpable and sensitive to touch. Myofascial trigger points often cause pain and discomfort in a specific area of the body, but they can also refer pain to nearby or distant regions.
When a muscle undergoes excessive or repetitive overuse, trauma, stress, or other contributing factors, the muscle fibers can become chronically contracted and form trigger points. These points interrupt the normal blood circulation in the muscle, leading to a decreased supply of oxygen and nutrients, accumulation of waste products, and increased muscular tension.
The pain associated with myofascial trigger points can manifest as a deep ache, sharp sensation, or even a burning feeling. It may be felt locally at the site of the trigger point or be referred to other areas, making diagnosis challenging. Trigger points can also cause a variety of symptoms such as muscle stiffness, limited range of motion, and muscle weakness.
Treatment for myofascial trigger points usually involves various therapeutic approaches, including manual therapy, such as myofascial release or trigger point release techniques, stretching exercises, heat or cold therapy, and medications when necessary. Physical therapists, massage therapists, or other healthcare professionals specializing in pain management are often involved in the treatment process.
Overall, myofascial trigger points are localized areas of muscular hypersensitivity that can cause pain and discomfort, requiring specific interventions to alleviate the symptoms and restore normal muscle function.
