If your claim is still denied after reconsideration, you can ask for a hearing, which will be heard by an administrative law judge. This is the point at which you may want to get an attorney who specializes in disability claims. You and your attorney can then plead your case in person and the judge can call witnesses. You'll also be able to look at your file and present new evidence.
Important: You could have to wait several months or even a couple of years until your hearing, depending on where you live.
