I've always thought foam rolling was more or less pseudoscience.
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.
