Hello, thanks for the query. Renal stone ( calculus) less than 4 mm on rt side and few small calculi left side. Pain in both legs and numbness, these bot problems are related to your diabetes so first of all get treated for this disease. Mind it that don t be careless about diabetes. Regular exercise and very fast( rapid) walking is the best way of regulation of this disease. Now Q is of calculi on both sides. In my many patients I have tried few drugs for calculi , but these drugs are Ayurvedic and since you belongs to India , you can take these easily. Tabs calcury 2-2-2. Tab neeri 2-2-2 i. e. four tabs three times a day. Drink plenty of water. GOOD luck. Dr. HET.
