The social security disability insurance is similar to long-term disability. It also requires complete disability and unable to work or extremely limited ability to work. Therefore, the applicant needs to be totally disabled, unable to work due to the medical condition for more than one year before the person can be considered as qualified.
You and I cannot decide for the SSA on what is the qualified medical condition and the evaluation of work ability. Social security considers both wage income and self-employment income.
The social security disability income is also offset possibly by other types of disability income. This is just a side note which may not apply to your situation.
It is suggested that you retain an attorney to help you. It is common in the field of social security disability to retain attorneys to help. The SSA will pay to the attorney directly from the payment when the case is approved. The attorney has no lien on the future payment, and possibly cannot charge more than 6,000 for a case.
You probably need to consult with several attorneys even eventually you decide not to retain any and continue to apply on your own.
Be patient; you are dealing with bureaucracy, but there is rule and regulations. You can also apply for hearing before the administration judge if your application is denied.
