I've had several kidney stone episodes about ten years apart, never discernibly related to smoking. I think the first was when I wasn't smoking anything. Because of the array of symptoms you report, you need a good diagnostician. Oddly, this trait doesn't occur in any particular specialty. My wife sees various doctors regularly, but one that has done the most "detective work" on figuring out some of her complaints is a dermatologist, and his diagnosis and sometime's prescriptions have been extremely helpful. In your place, I'd quit smoking, if possible, to get that variable out of the mix. Kidney stones relate to water intake, the more the better, but some beverages, especially tea, seem to promote them. Good luck and increasing good health.
