Hi, many thanks for the query!
You need to do- USG KUB to see any other stones, exact location of the stones, any hydronephrosis/hydroureter. also, do RFT, Urine (R/M).
Till then take antispasmodics, 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.
Do repeat USG KUB after 20 days to see location of stones, HN/HU.
See your doctor for lower abdominal discomfort
to know if its IBS
Wish you a good health.
