It's an excellent question. I wondered this myself after being confirmed by special MRI with dorsal root ganglionitis secondary to the Sjogren's. My neuro at Hopkins said there was NO effective treatment to date for this type of attack from Sjogren's. However, he said the dorsal root nerve block could be tried, just to see if it helped eliminate some of the pain. Until I see more evidence, I think I'm passing. Just the idea of messing with the dorsal root ganglia when there is known enlargement/inflammation makes me uneasy.

However, since you brought the topic up, I shall be watching this thread carefully to see what others have to say.
