Hello and welcome to HCM
Blood in urine, burning, and frequency of micturation with pain are mainly due to urinary tract
infection(UTI). Since your ultrasound
report is normal it rules out stone and obstruction as cause of UTI.
You need not worry just get your Urine cullture and sensitivity done(will take 24-48hrs) so that appropriate antibiotics can be started. Also get your blood sugar estimation done since patients with diabetes
are more prone for UTI
Visit your urologist
to get a physical examination done.
You should also drink lots of water and cranberry juice as it has shown to decrease the urinary infection.
wishing you good health
