When you say your calcium and sodium was high, I assume you mean they were high in your 24 hour urine collection. This is a common finding in stone formers. In the kidney, salt and calcium are
co-transported, meaning they are pumped out into the urine together, therefore, when you have a diet high in sodium and your kidney is pumping that sodium (salt) out, calcium is pushed out as well as an innocent bystander. The first piece of advice I would give you is to cut down the salt in your diet.
