Hi Littlepaw,
I'm so sorry for your reasons for being here but glad you found us.
Don't believe the crap about elevation improves the situation so it can't be CRPS.
I have full body CRPS and my feet respond to elevation too. This is the first time I ever heard of that. The burning stings seem to lighten when I elevate and my neurologist tells me that it's normal in my case.
Although I'm in a wheelchair most of the time I still go through the stinging and discoloration with cold burning.
I just had to chime in because I get worked up when I hear of a misdiagnose or something that I know is not right.
Forgive me for being so upfront. Maybe I should just be quiet...
