Make sure you have a good W/C atty on your side- they should be sending you for a second opinion maybe??
Due to the confusion by the drs about if a chiari or not and if it is due to the fall or what.

Get copies of everything for your own files- test reports, letters, take names of all that you talk to about your injury or case.

some attys are more interested in getting a % of the settlement than doing what is best for you....
read thru our useful stickys too.
