Oh, I wish I could say I could help you, but I have read several of your posts that you have left over the years and I would have to say, you certainly know a lot more than I do about this whole mess. I have not yet had a chance to try using any topicals, so there is not much that I can help you with. I do remember my original surgeon trying to offer a topical compounded lidocaine/ketamine creme for my, at the time artritis, but at the time I knew nothing about CRPS. I did not think it would help back then and my insurance would not cover it either. If I only had the opportunity to try it again.
For the most part, I just wanted to take the opportunity to say Hi! I am pretty sure that I remember others talking about topicals. I am sure someone will give their experiences here eventually.
