Report says every thing normal except 1) Right Renal 4mm lower Pole calculus 2) Fatty change sin the liver they say small kidney stone which can be go away from urine by drinking lots of water. I am little worried about its pain while passing it away . can it be bearable or do i have to take medicine? I consulted Gastroentrologist today morning who have prescribed me 1) Rinifol and 2) lactobacillus Lp299v Please suggest in future what should i do ? [/INST] hi there, a 4mm stone is too small to be operated on and usually passes out on its own with plenty of fluid, yes while passing down in the ureter it may cause pain and some painkillers like diclofenac sodium tablets can be taken to decrease the pain. The other medications can be taken as advised yby your doctor. Take care. </s>
