Have you spoken with your dr about the falls?

Why or what is causing the falling? Do you or dr have any ideas about it?
Is it leg weakness -do they just give out, dizzy spells, tripping?

It's possible it could be a new/additional condition causing the falls.

Are you thinking short term/temporary disability or long term - SSDI?

Disability depends on so many things and more or less proving that you are not able to do a/any job.
You might read up on our SSI/SSDI forum for info before deciding.
