Never heard of it. But there's no harm in trying something innovative.
I personally found that my best results came from techniques that were an extension of the coping skills I've learned on my own over years of dealing with pain in all its everday forms from menstrual cramps to dental surgery.
BUT, a lot of people have never had the chance to learn such coping skills and even those who, like me, have developed such skills are wise to keep an open mind about things that might well work.
