it depends on if it is sever enough to prevent you from doing your past work. and if you have a doc to back you up on ssdi. it will be a long haul for ssdi or ssi not to sound depresive but about 80% who apply get turned down at the first step. but win at the alj level. i would apply but get a attorney that will give you a better chance of a win. good luck and dont give up no matter what.
