Perhaps because Social Security Disability claims are almost never approved on the first claim unless the applicant is blind or missing limbs. The same is true for the rehearing. Only when a hearing is held before an administrative law judge, when you had better have a lawyer, are less obvious disabilities, like heart, lung, and mental problems, approved.
“Disability claims are almost never approved on the first claim unless the applicant is blind”
I can certainly understand the blind thing. I worked for the same company for 33 years and was “never” sick, but there were many times I couldn’t I couldn’t SEE going to work.
