I'm going to submit your question to Dr. Krusz, our pain specialist, to be answered in his "Ask the Expert" post. To be sure you don't miss his answer, go to Dr. Krusz's profile and subscribe to his SharePosts. Then you'll receive an e-mail when his answers are posted.(Note: If you've never been to the forum before, you'll have to register separately from your registration here on ChronicPainConnection. You can, however, use the same e-mail address and password if you like to make it easier to remember.)Karen
