Hi Phaedra!
I had a three-phase bone scan on my right hand and it was "normal". The dr told me that result and because of that I did not have RSD. He could not offer anything else, but it is not RSD. This jerk of a dr put in my records that I cried because I didn't have RSD and was looking for someone to operate on my hand. What a huge crock of BS. I specifically told him that I was there for an opinion (he was the 3rd) because the previous two drs wanted to operate and I did NOT want that, especially when they didn't know what was wrong! When he gave me the results, yes I cried because he couldn't tell me what was wrong with my hand. Needless to say, it was/is RSD and it mirrored over to my left hand.

There are times that people have had abnormal results with bone scans and it confirms RSD. They look at how the blood is flowing and pooling in that area. This is from the RSDSA website: http://www.rsds.org/5/news/2005/bonescans.htm

Good luck!!
