Well, one thing I can tell you. They want 15 years (I think that is what they said) of past work history, NOT 15 years of past medical records. I misunderstood that and sent them the name of every doctor I had seen for 15 years. They are only interested in medical records that pertain to the reason you are filing, not if you had LASIK or a fatty tumor removed or bunion surgery (unless you have bad arthritis in your foot, I guess).
So, on one hand, the lawyer thinks I'm an idiot for giving them 15 years of medical records because I misunderstood what they wanted, and on the other hand he tells me he doesn't think I have fibro fog. I'm sorry, you can't have it both ways, Mr. Lawyer!
