Social Security defines disability as the inability to engage in substantial gainful activity. The most important thing in a Social Security Disability Insurance or SSI claim is medical evidence. You must prove that you cannot work as a result of a medical impairment, and to do this you must have evidence of on-going medical treatment. If you are not seeing a doctor, many attorneys will not take your case until you begin getting medical treatment. It is true that Social Security will send you to see their doctors. However, these examinations are short, usually not very thorough, and rarely result in a person being found to be disabled.
