Thank you, Harley22 for that common sense testimonial. I finished my 5 days a couple of weeks ago with no noticible improvement. Now I know to not give up. (Not that giving up was really an option.) Also, I would like to ask a question: Are there any PN's out there without the usual numbness/pain complex? Just balance problems? My lack of symptoms has made it difficult to be diagnosed. Additional input would be helpful.
