I know this problem, I have the same kind of pain but my meds help me a lot; I use Amitriptyline. For many years, long before other symptoms of sfn started, I have to put my legs high when I wake up, for about half an hour or so. After that it gets better. Since a few months I have a footstool for my legs to rest, most of the time in the day I put my legs high, like an old lady but it feels better.
