I'm not sure.. but I'm going to follow your thread because I'll be doing the same thing soon. I do you you'll probably be denied at first, so you really have to stick with it. If I were you I'd go back through some of the other threads that involve disability and see what others have had to say.
Good luck.. I'm in your corner!!!
My disability was approved the first time around, but still it took almost a year.
An attorney told me the biggest problem with the disability process is confirmation. Often the medical records do not correspond with the patient's story. If you've discussed disability with your doctors and they support you, perhaps the process won't be too difficult. I also believe it helps to have multiple diagnoses, not just fibromyalgia....although that should be plenty.
Social Security and/or your disability insurance will obtain medical records directly from your doctors, so no need for you to try to get them (although you might want them to know what they will be sending).
Good luck and God Bless
