You really need to have good storng advocates around you. If you are disabled and unable to do any occupation than thats the criteria. Not that if you can walk or not, that only one aspect. Your pain, and level of ability is what should be evalated and reported to. Getting a strong lawyer is good. I would first try omy own with lots of help, but that just me. Maybe having a good lawyer is better ,at least they see you aren't going away, and that you are serous bout it.
