Social Security Disability claimants may qualify for Social Security Disability Insurance or Supplemental Security Income if they have a physical health disorder which is considered severe and is expected to last at least 12 months or result in death of the claimant. The physical health disorder must be supported by sufficient medical evidence from an acceptable medical source. Physical impairments which are considered disabling are listed on the Social Security Administration's List of Impairments. Common physical health disorders include: back injuries, neck injuries, diabetes, foot injuries, heart problems, carpal tunnel syndrome, diabetes, migraines and head injuries. The Social Security Administration evaluates not only the Social Security Disability claimant's diagnosed physical health conditions but also the physical residual functional capacity of a claimant to do work. If a disability claimant is unable to do any relevant work (work performed in the last 15 years) or be retrained for work (which they may be qualified to perform based on the age, work skills or educational background), the Social Security Administration will award the claimant either Supplemental Security Income or Social Security Disability Insurance benefits.
