I'm so sorry you're having to apply for SSDI.

Many mistakes are made in these vast systems. The person who told you your claim had been approved may have been looking at a computer screen that said you had been approved, and later on it changed and said it was pending. Someone somewhere decided that more information was needed, maybe.

I'm just guessing but it's based on the problems I've seen people having dealing with computers and with lots of information coming at them. I don't think anyone intentionally lied in this case. Social Security is an overloaded system, and it's amazing to me that they do as well as they do.

I hope they told you WHAT information they still need. You might be able to expedite the process if you know that.

If you have a neuro who can write a supportive letter, that might help, but that's probably already been done. Any other doctors who might chime in with more supportive letters--ophthalmologist, ENT doctor, primary care doctor, etc.?
