Hi Big Bug and Mrs. Big Bug,
So sorry you have RSD, that's a long time. Welcome to this forum. You will find so many caring fellow suffers of RSD. We all have lots of questions and get so many answers and different experiences. I've learned so much. Coping skills is a big part of living with this.
I'm not personally aware of tDCS. What is it? How does it help? Thank you and I hope someone is aware of it and can answer for us. Take care, Loretta
