Since the kindey stone is 7 mm, so the symptoms seem unrelated to the kidney stones
. Since you are having pedal or leg edema, hence your cardiac, liver and kidney functions need to be assessed for which I suggest you to consult a physician immediately. Abdominal causes like irritable bowel syndrome can also cause such symptoms. Common symptoms include abdominal cramping or pain, bloating and gassiness, and altered bowel habits(alternate constipation and loose stools).
