Pain is thought of as a physical issue, and of course it is. But a big part of pain management is a mental issue — psychologically dealing with pain to minimize its sensations are as important as trying to reduce any physical causes. So the subject of pain could be listed in both mental health and physical health categories. Or, if the techniques to manage pain are non-traditional, then alternative medicine may be the best way to categorize pain management.
The traditional way to deal with pain has been prescription painkillers. But such medication is powerful and for many people brings with it adverse — sometimes very adverse — side effects. That’s why many people are trying — and having success with — alternative methods such as hypnotism, meditation and CBD oil.
