Pain plays a vital, protective role in our lives. How much pain we feel and how much pain medicine is required depends on our genetics and possibly our sex. Females feel more pain than men, but require less pain medication. While most people recover from an injury some five percent won’t. They’ll go on to develop chronic pain. The factors that determine this are both environmental and genetic. There is no single pain gene, but there are not hundreds of them either. Scientist are looking for a particular type of gene that exists in different forms that can be inherited and of those genes there are anywhere from five to twenty tops. Pain is psychological, there is all this neural activity going on but it can always be trumped by culture, attitudes and behavior.
