I am going through this process now, and it sucks. I am on short term now a few months, and the process is terrible. my disability insurance reviews my case every month or so to determine eligibility.
i am in process of scheduling a neurophysc exam myself to take it to the next step. unfortunately, i wont be able to get in for that for close to two months.
I need to go back to work too, the financial loss is starting to be crippling with all the medical expenses. (and i only have been treating for a few months - can only imagine the impact after years.)
