Hi, many thanks for the query!
Pain can be due to several causes more commonly due to stones,
infection of the urinary tract
is there if there is infection but subclinical infection
doesn't cause fever.
You need to do- CBC, RFT, Urine (Culture & Sensitivity),
Random blood sugar level, USG KUB.
Start appropriate antibiotic as per report, take antispasmodics, pain killers with your Urologist's opinion.
Drink plenty of water so that at least 2 litres of urine is voided in 24 hrs.
If diabetic, blood sugar levels must be in good control.
Wish you a good health.
