Hi Roz,

I came across it just the other day. I found an interesting site that explains things to about my basic level :

"The NIH does not recognize any treatment as being satisfactory for the burning dysesthesia. By comparision, posterior column pain is likely to respond to various medications including opiates, anticonvulsants, or hypnotics. These same drugs may sedate the patient to the point where pain is less of a problem, but the levels required for dysesthesia are so high that the patient is usually sedated to the point of not being able to function. There is hope that some of the new N type Calcium channel blockers, such as Prialt or Ralfinamide will treat central pain. These drugs have been shown to benefit pain from injury to peripheral nerves, but no double blind studies exist to show that they are effective for pain of central origin."

Thanks for posting that, sounds like it may be the next research to keep a good eye on.
all the best,
