Vrae, I am so you have this worry on top of RSD. My son had an accident 2 years ago and his prognosis was not good. I didn't leave the hospital for 30 days. It was an hour from my house and I just couldn't leave. He had gangrene inside the bone of his leg and had 7-8 surgeries. He has recovered but it could come back any day. It can lay dormant for 60 years or longer, one one day come active. He just turned 22. You are all in my prayers.
