The patients commonly wonder how we detect the trigger sites. And how we deactivate the trigger sites.

First, the piece of information comes from the patient. That is extremely important. And that is where the headaches start from.

Each patient has at least two or three trigger sites where the headaches start from.

We ask them to point to that area, then we put the constellation of symptoms as well as findings from listening to the area with a special device which is called an ultrasound doppler, we detect the trigger sites and deactivate them.
