What is a Trigger Point?
When you experience pain, spasm and inflammation in your muscles for any given period of time, knots can form. These knots are known as trigger points. As these knotted bands of muscle fiber remain tense, they can lose their ability to relax, and continue to stay tied and bundled up, generating additional pain and discomfort.
These tense fibers cause irritation to the nerves around them, and can produce pain, otherwise known as referred pain that can be perceived elsewhere in the body.
The muscles of the mid and upper back are particularly susceptible to the formation of trigger points, which can lead to chronic headaches, and neck and shoulder pain. Lower back muscles are also a common site where trigger points may crop up.
