The Social Security Administration defines a “disabled” person as one who is disabled by a physical or mental disease, injury or condition (or combination of those three) for at least one year; and that disease, injury or condition must prevent you from performing any substantial work (not just your usual work). How pain affects your work also is considered. Meeting these requirements can be difficult because the Social Security regulations require medical documentation (such as X-Rays, tests, or other forms of medical documentation) not just a doctor’s opinion. The Social Security Administration may even require additional examinations (at their expense). If you refuse to cooperate in these extra evaluations, your claim likely will be denied.
