Thank you, Sandy. My daughter is only 13, so I'm thinking it would be best to start with the Lidocaine, then we can work up to the Ketamine if we need to. However, I don't want to put her through it if the Lidocaine doesn't give good relief. She has not had relief from nerve blocks; she has had 5 out of the series of 6, each providing only a few days relief of decreased pain, but the pain was still there. She is so fed up with getting poked and injections, trying this and trying that, with nothing working. I just hate to put her through it if it won't be enough.

Why did you switch from the Lidocaine to the Ketamine? Did the first rounds of Lidocaine work and then stop working?
