i think the best way to monitor the original phase of CRPS ans the stages of progression is to set up a journal that allows you to write down all of the good and the bad you have encured overtime. this journal will allow you to sit down with your doc and explian where you are concerned about srecific concerns. in your journal i would recommend you add pictures of the changes you using the best art skills you have (even if it is just stick figures). the problem here is that so many doctors struggle to believe that your pain has actualy transfered from one are to another, and most important the damage it causes. the only way a doctor is going to take your new injuries seriously is because so many frauds have infiltrated the system and made up everything in hopes being of able to continue. now the gut reaction for the majority of md's is to take the complaint of a shift of complaints as nothing more than someone who is trying to get something their old injury no longer requires so they add additional ailmwnts to force a continued level of care.
anyway the only way to distinguish is to show your doc that you have a problem is by compiling evidence to the fact. most drug seekers wont waist their time because they are focused on other things. a journal also helps doctors to see what is and what isnt on your current regimine.
