Dean, the problem that's going to come up is that you were capable of working as a PE teacher within the last year, which is a much more physically demanding job than sitting behind a desk. Since your BP was also a factor in why you were unable to continue working, that also will make such a claim appear less credible.

It makes no sense that you don't have a placard, at least for medical appointments if walking is causing you problems. Also, the first step a patient with trouble walking would usually start with a cane to determine how much that will help. Then they'd move on to a walker, and then a wheelchair if they're incapable of ambulating very far.

You need a doctor to spell out your work restrictions and or limitations. Again, having a Functional Capacity Evaluation will help your doctor/s determine what those restrictions and limitations are.

While working from home is certainly an option, telecommuting or working online aren't currently factored into the jobs Vocational Experts consider for SSDI eligibility, based on current rules and regs. This may change at some point.

Swimming is considered the best exercise for those that have problem with weight bearing.
