Don't know why I neglected to mention this on my previous reply- I'll blame RSD memory problems

. I didn't know I had RSD for the first year because I got pregnant just weeks after the surgery that followed my injury. My pain improved to almost nothing, and I thought the surgery had worked, and I was done with the pain. About 6 weeks after I had my baby, the pain returned and my very confused ortho sent me to my PM doc who figured out that it was RSD. I did some research, and it turns out that it is VERY common to go into complete remission during pregnancy. Some doctors think it's because this is an auto-immune disease as well as a neruological one, and when you are pregnant, your immune system acts differently to protect the fetus from being seen as a foreign body and being rejected. Others see a hormonal connection. I think it's probably a little of both since so many of us see a hormonal connection around our period.
I have read that osteoperosis is one of the symptoms in stage three of this disease. it is apparently visable on x-rays after enough time has passed and the disease has progressed. I would talk to your doctor about this and tell him/her about your family history. Maybe you could take a calcium supplement to protect yourself. Good luck!!
