I don't have any insight but hear and understand yor fears. I guess and I am going to be probably getting a scs but I am going to ask what kind of relief will be there for me if something goes wrong. So maybe you can ask them if you do go in a flare what meds or treatments will be available? Does your ortho know a lot about rsd? If not maybe finding a doc or one of your others to inform him/her so it is like a team approach. I am sorry you have to go through this.
