I don't think there's much science, pseudo or otherwise. It's just experience. In fact, no one knows what "trigger points" are. Attempts at science in this area have not made this clear. Many people talk about breaking up scar tissue with soft tissue work, but that's just silly. It's an empiric thing. Many people feel it helps them. I certainly know of no harm that rolling on a foam roller, tennis ball, lacrosse ball, softball, stick or any other implement that is used. When the risk of something is low, the risk-benefit ratio is high. I say, try it, if you like it do it. You should probably try it over a few weeks, not just one time.

I roll intermittently using either a lacrosse ball or a medicine ball, mostly my back and glutes. I have no foam roller.

If it helps you then by all means. I actually used to foam-roll in the morning. It didn't seem like there was any point to it though so I just stopped. I found exercise alleviated discomfort more so than foam-rolling.

There have been no proper experiments. However poorly documented cases show it helps. I have tried it myself and it works. It's kind of the same as getting a massage. It is poorly understood though.
