In addition to the tips previously posted for getting your disability benefits set up, you can pretty much expect that your initial application and reconsideration will be turned down by Social Security, (unless you are missing a limb or your disability is very obvious and dose not require a medical report from a physician to verify it).
Don't let this discourage you! This is par for the course. Be prepared, (keep good medical records and make sure your doctors do too), to go all the way to Appeals and have an Judge award your Title II Social Security Disability Benefits, not to be confused with SSI, which is welfare. SSA Title II,(SSDI), is based upon what you've paid in over your entire working life. All that SSDI tax that was taken out of your check, the rate of pay, etc., determines your benefit amount up to the benefit limit, which, in 2012, is approximately $1783/month.
