Wishing you heaps of luck!! For my case I had a very extensive photographic display of the undeniable changes that have occured due to CRPS.
They found this evidence the most convincing. You have a couple of weeks still, if you are like me you should be able to gather plenty of evidence of colour changes, swelling etc in that time. Is there anyway you could get thermographic evidence? Here in Australia much value is placed on a thermogram that shows the vasoconstriction causing temperature changes.
Good luck
