There a lot of money in big pharma and there are solutions to heating up areas of the body developed for people with tense backs.
It's no absolute heuristic but it looks to me like a topic that's open to big pharma intervention. That means there likely research out there that gives a better idea about whether it's something worthwhile to do then simply following folk remedies.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
