Dear friend, welcome to HCM.
Is your pain constant or comes on and off like a colic?
Was an Xray KUB or sonography
done for the stones?
Have you passed adequate urine?
There could be another one.
There could be complications like dilatation or infection.
You should see your doctor to get evaluated for anything serious. Urine routine, USG and Xray KUB will be needed.
Take OTC pain killer like paracetamol
Drink lot of water if no kidney
failure declared by your doctor.
Take care and keep me updated on your progress.
Good luck !!
