Hi!
Recurrent kidney stones are found renal tubular acidosis, medullary sponge kidney, Dent's disease (genetic disease of the kidney), hyperparathyroidism, primary hyperoxaluria and Crohn's disease. Diet high in animal fiber, dehydration, and low calcium intake can also cause recurrence of stones.
Please discuss these possibilities with your doctor and see if you suffer from any of these disorders. Treating these would help reduce pain.
