I did try flector patches for a short time and I wish I could remember better but I believe that I stopped them because they didn't work for me. I don't remember any side effects being an issue. I also had the problem of keeping them from falling off- any kind of patch on the knees does not want to stay once you start walking.

I hope you get your compounded cream too. I tried a compounded ketamine cream- is that what this is or is it something else? It did take quite a bit of time for me to get mine too. But I think that's good advice that once you get it, you can alternate it with the flector patches.
