I would probably have it done, even though mine was negative.... the doc that ordered mine also ordered an emg... which also was negative. She was so sure I did not have RSD and was faking that she was nearly jumping up and down. I asked how I could fake swelling, cold, red, shiny, ridged fingernails, hairy area on arm.... she said if the bone scan was negative I did not have it period. I nearly ran out of her office and never went back. I went to Clev Clinic and my doc there doesn't order either test, considers them a waste of time.

But, if your lucky, and it is positive- it will help you prove your case.

Mine was done 2 months into having RSD. I wonder if I had one now, years into it, if the result would be positive. I am having a lot of problem with the bones in my feet getting stress fractures even though my bone scan that they give women is normal... makes me wonder if the RSD in my feet has left my bones weak there.
