I am sorry you are having to deal with this. I too would be cautious. I am not saying this is for you but I was told by a dentist I had 2 caveties. Anyhow the way he stated it was weird. It was something like I could wait to fill them if I wanted but he would do it cause it is not big deal. He was a very expensive dentist like unreal so he makes a lot of money. Well anyhow I am having orthodontic work and was going for opinions and taking my xrays etc to all. I found out I did not have any cavities. This happened to a lady I know too. Do you think maybe another opinion to make sure? If you hae to get this done I would really talk to the person who is doing it and explain to them about your condition. Some may say they know about rsd but in reality they don't. I hope you feel better
