It worked for me once. I woke up one morning, and when I stood up it felt like someone had a knife in my hip. Over the next couple days the pain migrated down my leg. I went to my doctor who gave me Vicodin and told me to rest. It didn't help and one of my friends suggested her massage therapist who works in the best massage calgary lad so I scheduled an appointment. Luckily after few sessions my pain has gone. I think it definitely has benefits for acute injuries and things like postural pain and overuse injuries. Of course, it's better to apply to proven and well-known specialist.
