###Human: Why am I getting pain during pee? Is it due to the kidney stone? ###Assistant: Hi. You may have sudden pain due to the passage of kidney stone from the kidney to the ureter. It also causes difficulty in passing urine. A kidney stone of 5 mm can move out soon by 90 %. Drink a lot of fluids and continue the medication prescribed by your doctor. If the pain continues to be severe or if you have vomiting, or if you cannot pass urine for more than 12 hours, I suggest you revisit your local urologist soon.
