What Is The Difference Between Fibromyalgia And Reflex Neurovascular Dystrophy?

I have been diagnosed with RND (reflex neurovascular Dystrophy). But, my Aunt has Fibromyalgia. We dont have much difference. So I was wondering if I have Fibromyalgia. But I don't know the differences between the two. Does anyone know the difference?

Answer

That's a really interesting question. There is is definitely overlap between the two and one wonders over time how the medical profession will view these disorders. Both often start with a minor injury that seems to trigger problems in pain processing. Both appear to involve sympathetic nervous system problems.

The main difference for me is how localized they are. While RSD can spread from one area into the other it often displays a kind of intense localization is not found in fibromyalgia. For instance, in RSD the affected limb can swell up, turn colors, become stiff and pliable and develop bone loss. Swelling in FM does occur in some people it is not nearly so prominent, color changes that occur as often and a core definition of the disease is that it affects multiple areas of the body.

I wouldn't be surprised, though, if these disorders grow closer to each other as we learn more about them; one may very well be just a variant of the other. Good luck to both of you!
