Hi, many thanks for the query!
You need to do certain investigations- USG (Abdo-Pelvis), X-ray KUB,
Sr. creat., Sr. BUN, Sr. Uric acid, Urine (Routine & Microscopy).
You haven't mentioned about exactly what kidney
there in your family.
For time being, you may take anti-spasmodics, pain killers, diuretics
with your doctor's opinion.
Drink plenty of water so that at least 2 litres of urine is voided in 24 hrs.
Wish you a good health.
