A muscle fascia Trigger Point is a hypersensitive point on a skeletal muscle located in the muscle tissue or associated fascia. It is painful under pressure and can cause a characteristic pain sensation and symptoms related to autonomic nervous system functions.

Types of trigger points
There are three types of trigger points causing muscle pain:

● Active (basic), the presence of which causes pain, restriction of movement, pain during pressure or after stretching of the muscle.

● Satellite trigger points, which can be created around an active trigger point and are not so painful. They disappear after the basic-active trigger point has been successfully treated.

● Latent trigger points, where some active trigger points may develop, resulting in joint movement restriction and muscle spasm, while sometimes they also cause pain. When does this happen? When a musculoskeletal problem (e.g. cervical stiffness) is treated with medication, conventional physiotherapy and rest, the patient initially shows improvement but after a short while the symptoms re-emerge, because the possible trigger points were not identified and subsequently deactivated during the treatment.

The pain path may not always be related to the span of the muscle.
