Your daughters RSD could have spread. Does she have the same symptoms in her shoulder? If so please contact your PM doctor or someone who can advice you on what to do, your doctor may want to see you. Tell your daughter to keep touching her shoulder so that it does not go hypersensitive. She will probably need to start doing gentle excersises too (thats what I did when I had a spread), it will be painful but it needs to be done.

My name is Alison I am 12 years old and I suffer from RSD in my left leg. I used to have RSD in my right arm too but it is now fully recovered, thankfully. If your daughter wants to talk then I am always here. I will send you my email address via PM.

Take care
Best wishes
Alison
