Can I get SS disability for side effects of prostate cancer surgery and radiation treatments such as incontinence and long term pain ?

Social Security disability benefits are based on your inability to do any job, not just your current job.  You can apply at www.ssa.gov. Social Security Disability Insurance is like taking your Social Security retirement benefits early.  If your application is granted, you will receive the amount which you would have received at full retirement age.  After 24 months you will be eligible for Medicare. You can handle the application, any request for reconsideration (ask for an informal conference) or redetermination on your own.  If you must appeal to an Administrative Law Judge after taking these steps, you may want to be represented by a member of the National Organization of Social Security Claimants' Representatives.
