I have had issues with kidney stones since getting RSD. I too think it has more to do with the change in lifestyle since I've had RSD...though the only thing that I did different when I first started getting them in terms of diet was that I cut WAY back on soda and was drinking gatorade almost exclusively. Who knows...but there's no family history of kidney stones in my family and I had never had them before. Thankfully I have been able to pass them all without needing any medical intervention...but I was terrified when I got the first one because of how bad the pain was and I had no idea what it was.
