I have seen 3 new internist since I have had this condition for the hopes of getting one to manage my case. Well none have done that. They also say they don't deal with pain and to see a pain specialist which I have or refer me to another specialty. So now I just use my internist for normal medical issues not related to the rsd. I think for the rsd it is so key to work with someone who deals with rsd a lot.
As for your swelling did you notice more when you started any new meds? Did you start the prednisone after the swelling? What about other meds like neurontin etc? I was told on here that causes swelling.
Have you thought of going to a hosptial such as Hopkins or Mayo? I heard and I don't know this for sure that a group of speciality doctors look at your case. I think what is so frustrating is that when you go see a specialist they don't go outside their specialty and often don't consult with your other doctors properly. Sometimes i feel there are connections that are missed.
I am sorry I don't have more to offer.
