[used to be]

Hello to all. In spite of several months of physical therapy my rsd leg is now a half inch shorter than my other leg. I don't understand how this happened while I was working so hard to prevent it from happening.Does anyone know if there is anything I can do to fix this or at the very least to keep it from getting worse? I've tried 4 different therapists, one of whom specialized in rsd and still this is happening. Is there anything else I could try. I've only had rsd for 1 and a half years and I'm astounded at how much mobility I've lost in such a short time. I'm frightened to think about what lies ahead.Any input would be appreciated...thanks to all.
