Trigger points can be found anywhere throughout the body but often give us most trouble causing neck pain and low back pain, both regions which can be implicated in the development of ‘muscular tension’ headaches.
Trigger points are the tender almost nodular feelings in generally taut bands of muscle. They are very good at creating a sense of vague achy, deep dull or boring pain, even sometimes sharp and ‘nervy’. They also result in stiffening and weakening of muscles such that they cannot do their job in supporting an upright posture for example.
Have a feel of the muscles between the neck and the shoulder, those that may feel tense when sitting all day or stressed. If the muscles feel ropey, stringy or hard with one or two spots that are exquisitely painful to press on, these are likely to be trigger points in your upper trapezius muscle.
