To a new, modern way of life belongs new modern kind of illnesses too. While people in the middle age died because of plague, we suffer from cancer.
Back pain is of course not closely that serious as cancer, but belongs to our century just like that. Statistics say that 8 out of 10 people suffer from back pain at some point if his/her life. As about everything that common, we have all sort of “knowledge” about we should or we shouldn’t do. Again just like in the middle age, superstitions in many cases.
Here you can find a slideshow about the most popular beliefs and the refutation of a few myths. Worth to look through!
