I have 3.4 mm stone in left kidney and small concretions in right kidney. I am taking proper medicines and drinking 8-9 glasses of water per day( i am trying to increase it). But I am very very confused about food items. Google shows almost all the food items to be avoided. Currently i am not eating tomatoes, rice, okra and brinjal. Please tell the real food items to be avoided while treatment and after the treatment so that i have less chances of stone in future. P.S - Can i take whey protein like 1gm in stones. I never took it before but currently i have started workout for weight gain hence i am asking.
