I have found it extremely helpful. It's not a magic pill but I always feel a LOT better after a session. Part of the point is to help relax you, that is almost half the battle. Tensing usually causes more pain which causes more tensing and yet more pain, a nasty little circle. It also helps to learn to try and focus beyond or above the pain. You still can hurt but for me it lessens the pain and makes it easier to cope with he pain I do have.

Also, as we all know STRESS is a killer when it comes to spiking up your pain. The relaxation helps with that too. It helps to cut off another vicious little cycle
