I really like this video clip. It explains the process of trigger points very well. Self-treatment helps and we must take ownership of our pain as often as possible. Below is also an article related to trigger point dry needling, which I think explains how it can be sorted out quickly, permanently and, I think, better.
And for the academic article:
