Primary trigger point
Primary (active) trigger points are pressure sensitive areas within a sticky muscle, often with tense fibers. Symptoms can often be triggered with pressure to a single point and tend to radiate. Patients describe the pain both in resting as in activity during anamnesis. This relates to the common active trigger points. Typically trigger points can be found around the pelvic crest and on the outer side of the leg, radiating into the foot. Cause for active trigger points are often constant tension of the muscles, as inflicted by today’s society: Sitting at a computer or standing at a desk are single-sided strains which ask the same muscles to work statically, leading to chronically leveraged tension.
Secondary trigger points.
Additionally there are secondary trigger points. These form when one or more systems of a musculoskeletal system do not work properly. For example, if a joint cannot glide properly, a muscle will force this gliding to ensure a human can move normally. But this wears out the muscle, keeping the tension constantly at a very high level, which leads to so-called sticky muscles with high tension, resulting in trigger points.
Studies confirm that untended trigger points are often the cause for radiating chronic pains. They are often overlooked as trigger points in the lower back show similar symptoms to a slipped disc and disc hernias.
The mechanism after puncturing can be explained with the dissolving of the stickiness. Additionally the micro trauma is registered in the brain, initializing increased circulation. The healing process is kicked-off and tensions dissolve. One to five sessions are required.
