I had it in my foot after I broke my 5th metatasal(sp?). It was many years ago and wasn't fun! I did finally get rid of it but from the time I broke my foot to when I last had a symptom was 1 year. It is slow going. I didn't realize that they had a new name for it.
Taking the medicine for it is new too. They didn't have that for me. I also loved(being sarcastic) how they told me that there is no set cure, they just try things to see what works!
I had severe pain in my foot and it would alternate between being cold and blue to hot and swollen.
The things I tried, lots, I may have forgotten some. They are: moist heat, physical therapy(ultrasound, electric, exercises), biofeedback, nerve blocks(they probably helped the most, but I dislike them!)
So keep working at it and just know that it is slow! But you can recover from it!!!!
