Joe, someone else told me they got disability for TN in 3 months. They used Binder & Binder Disability Law specialists. Also, you have to keep a pain diary and be very specific in it. Here is a link you can look at that I have come across in my research...good luck and I hope you get some relief soon...

Joe -- you asked for suggestions. Mine would be to get your lawyer to tell you VERY explicitly how many hours you can work before you are no longer considered "disabled" or have only "partial" disability within the criteria of SSDI. Generally, the disability authorities are absolute sticklers about not paying you disability if you can work at all in a manner that supports yourself or your family
