I have always been told by doctors RSD is only a symptom of something greater. Since I have had RSD I have had 10 infection, and 4 new health conditions -- IBS/acid reflux; endometriosis; chronic infection and Metebolic tremors. A friend of mine has also question if RSD, fibromyalgia have a genetic link...if a mutation in the gene causes familys and people more susceptible to chronic pain. In my family I know of 3 people with chronic pain, me, my aunt(my moms sister) and her daughter.
