It would probably be a good to start the disability report online and spend some time putting together a thorough and complete summary of treatment and sources. SSA needs to contact your treating sources to get the records. It is important to provide good addresses and the approximate time period of treatment and general types of treatment. You don't need to document each exam date, but the approximate date you first went to Dr. So and So and the approximate date you last went to him, how often, what he was treating you for and the types of tests.

The more thorough your initial application and disability report, the better chance you have of an initial decision that considers all your problems. Your local office can and will complete a disability report and take your application if you walk in today, but unless you are prepared, there is a good chance that because of limited time, the disability report may be missing some important data. And sure, you can submit it later, but I personally think it is best to submit a good disability report at the outset rather than piecemeal. Employees have limited time to spend reviewing your forms and having everything at the beginning is better.

You might also want to go to socialsecurity.gov and read the Blue Book about your specific medical problem and tailor your disability report to those specific symptoms and test results.

Focus your allegations also on your limitations in terms of being able to work. Don't say "Can't stand a long time". How long is long? Rather, "Can stand/walk for 10 minutes and then need to sit down". Don't say "Can't carry too much". Say "can only lift 5 lbs".
