After working for about 20 years, I am in a process of the retirement based on my disability: C-5/6 complete with some recent complications. I stopped working 2 weeks ago and am in FMLA (medical leave). So, I am still getting paid from my remaining vacation & sick day. I have never considered a lawyer for applying the SSDI, but a LTD insurance company mentioned/suggested the service from an attorney's office. As a C-5/6 complete, does anyone see any necessity of the service from an attorney to apply (and get) the SSDI?

Another question would be if I can apply for the SSDI at this point (when I still get paid) or if I should wait until I spend all the vacation & sick days.

Thanks in advance.
