Anyone familiar with a Lidocaine infusion?

One of the new gals on the Fibro site was asking about this. I have never heard of it, but it sounds promising. Has anyone had this treatment?

Very interesting, and a WONDERFUL idea !

But in it's current forms, isn't it pretty short acting, and pretty localized (think dental-numbing)? It shows in that article that they are setting it up in the abdomen, but what if the pain is in your feet? And it's metabolized by the liver and kidneys, making it a little worrisome for long-term use. Even the topical Lidoderm patches are only worn for 12 hours, due to the risks. There are other anesthetics that are safer and longer-acting, I wonder why they aren't looking at those first?

Sorry, I don't mean to be negative, just thinking out loud.

I really hope this is an option for me, I can't wait to find out !!
