Hi, High, and welcome! I received SSDI without an attorney 15 years ago and it has now changed to straight SS since I'm 65. I never had a review. I think it depends on what you are getting the SSDI for...if it can be something that can get better. My illnesses are permanent so they didn't bother with me.
Be sure to read Fibro 101...the first thread on the forum. There are links to good info and you will learn a lot. We do have to be our own advocates with this illness.
I'm looking forward to getting to know you better. Don't hesitate to ask questions because we are here to help you. Hope to hear more from you soon.
