To be honest, what you describe doesn't sound very much like RSD to me, but that may be because you didn't describe everything you've experienced. Did this start off with some kind of trauma? Was it first located in the area of your body that experienced the trauma (especially if it was one limb)? Do you have severe pain from very light touch (like air movement or light fabric brushing your skin)? Is the pain of a burning nature?

RSD starts in one area usually following physical trauma to that area, and it can spread to other parts of the body...but only a very unfortunate few end up with it in their entire bodies, and this process usually happens over months or years. It's a rather terrifying process. After time left untreated, RSD can be associated with progressive physical degeneration, such as osteoporosis and deformity of the effected limb(s) (not everyone gets this part, but many do, especially if not treated). Also, there are other sometimes overlooked symptoms such as nail and hair growth abnormalities in the effected area (some people get overgrowth, some get little to no growth at all).

Sometimes fibromyalgia is secondary to another chronic condition, although it can definitely exist on its own. It's also often associated with myofascial pain syndrome, which can cause extra pain in more specific areas.

I hope this helps you. I'll be looking out for your answers to the questions above! They're not the only questions to ask, but I hope they'll give you an idea about what to talk to your doctor about.
