Sorry about your pain and I hope they can give you the answer u deserve.
My exhusband had RSD or CRPS now they say in both feet after some failed foot surgeries. It was a process of elimination that came to the final DX. It was very hard on him physically and emotionally as the RSD progressed ending up in a motorized scooter.
I took care of him for years but finally had to leave after he started to become abusive to me and my son.
Now Jenna I am not telling you this to scare you but you want some info on RSD and yes I lived with my ex for 10 yrs and he had RSD for 7 of those years. It was a very bad condition I would not want anyone else to have it at all.
Now you have a great support team and probably access to good Docs so I hope they will help you and take care of your shoulder and help with your quality of life issues. Good luck to you in your studies.
