Your neuro may be able to get info from Dr Fugedy of Atlanta pain doctors.com Brain Stim Clinic in Atlanta Ga. He's the go to doc if you want to buy unit and treat at home. He charges a fee because he's the oncall doc to follow your progress and make changes when something doesn't work. He may be willing to talk to your doc to avoid you having to go to him. My friend and I went to Atlanta and went thru the process of treatment with tDCS and it did nothing for us. That's not to say it won't work for you. There are people on here that it does help so do all you can to get whatever works for you. I have a unit for sale if anyone wants it. You'll need new pads but that's the easy part. Good luck in your search and by all means have your doc call Dr Fugedy. You could also write to him at (Dr.Fugedy@Gmail.com) see if he'll write back.
