Hi Geordie
CRPS and RSD are essentially the same beast doing the same nasty things to us... There are two types of CRPS, Type I (no obvious nerve damage) and Type II (known nerve damage). But the symptoms and effects are the same, and basically RSD is CRPS/CRPS is RSD. There is a school of thought among some doctors that splitting CRPS into two types isn't that helpful for the patient, as it makes little difference to the treatment we need...Hmm...
RSD is the old name - it used to be called Sudecks Atrophy (?) and a few other things before RSD. Then qute a few years back a panel of experts decided to rename it CRPS as this was felt to be a better definition of the disease. Obviously there is contention about that decision

but I do just wish all the doctors would call it the same name, then all the patients will call it the one name, and we can stop having the confusion of two names.
Good luck to you Geordie, hope you have a good evening.
Bram.
