You have to get checked by your doctor. A doctor can perform a blood test or urine test to determine whether your kidneys have damages to them.
In particular, the doctor looks for a blood test called creatinine. If the creatinine is elevated, then there could be renal disease. Also the doctor checks your urine to see if there is blood or protein. Blood or protein in your urine might indicate that there is kidney disease.
