It may or may not have an observable cause. Trigger points are highly irritable spots in a muscle, and contribute critically to chronic pain. Dr. Bronson Ong s work is to stop them from irritating the muscles in which they reside. It seems that trigger points are laid down inside a muscle, when the muscle is insulted - by way of road accidents, injuries during sports, occupational hazards, and disease. Trigger points may even arise in an infant during its passage through the birth canal.
Trigger points can arise anywhere in the musculo-skeletal structure of a person.
In fact trigger points are formed before a baby is born. Trigger points lie doggo inside a muscle unless certain conditions are existent to cause them to emit impulses that will throw the muscle into a spasm. Such conditions can take the form of emotional or physical stress. An example of chronic ache is backache. A muscle which contracts for too long a time or too frequently may become shortened and thus interfering with function, posture and balance.
