I developed crps 10 years ago, several years after an accident. The site of the pain is on right foot going up my right leg including my wound from my accident. They said it was a result of my accident and my sympathetic nervous system messing up. You all would know about it if you have it. But I am taking my oxycodone and Fentynal. I have been putting lidocaine patches on it hoping it would numb the burning. I also been taking my Geodon again because I thought it would help with nerve pain. Nothing is dulling the pain. Can anyone tell me what they do to help with the pain site. I have been in remission with it for years. The burning is worse than before. I don't have a tens unit anymore. Now the wounds and skin is turning color, getting cold and burning. I want to relieve the burning. Anything that can help that that you may know of would be appreciated.
