We have been having some positive responses to the application of lidocaine. I have often wondered why a person struggling from intractable hypnic jerking seems to show no evidence of jerking while under anesthesia. This article might explain why.
One facebook group member received injections of lidocaine and experienced a few days of relief from her jerking. She then experimented with 5% topical lidocaine and shared her success with others in the group. There are a handful of group members who have also had success with this. It seems that we might need to find appropriate areas to apply the lidocaine. According to the below article, we might best search for areas that have been scarred from trauma. Below is an excerpt from the article.
