Definition of Relation. A relation is a set of ordered pairs. This seems like an odd definition but weâll need it for the definition of a function (which is the main topic of this section).
Classic (Swedish) massage and Thai massage have been proven to relieve chronic lower back pain. Classic massage for lower back pain is a technique that relaxes muscles in the area through the application of pressure. The area is rubbed in the direction in which blood flows back to the heart. Thai massage, on the other hand, is a technique that pulls and stretches the area of the back and neck.
Epsom salts, and medicated bath salts, can be wonderful for lower back pain. Soaking in a hot bath on its own can be a help for many people, so the addition of the salts can work wonders on back pain. This is because the salts have almost magical ways of relieving muscles that are strained and stressed.
