Sorry that it is so hard for you to get good treatment. No matter what system you have though (UK, US, other countries) there are always pitfalls. Whenever a country discovers a perfect system they better share it with everyone.
But on the tDCS thread there's a post towards the end...either the last page of second to last that goes through the OTHER therapy she did when the spread started (desensitization, physical therapy, mirror therapy, etc). It was a pretty intense program and even disregarding the tDCS treatments I personally think it would be successful for many people in the early stages of spread. Don't get me wrong...the tDCS is probably a part of her success...but it is all the other stuff that may be really halpful especially if you can't get in to see the doctor any time soon.
