Its almost certain you got a urinary tract infection
. Signs and symptoms described are compatible with both a bladder and kidney infection
(acute cystitis and pyelonephritis). The main fear in this situation now is a kidney abscess and kidney failure.
It is urgent you met a nephrologist
for urine culture and sensitivity tests and an abdominal ultrasound. Serum urea creatinine levels, blood cultures, markers of inflammation, complete blood count
and an electrolyte panel are also very important.
I suggest you organize a rapid appointment with a nephrologist, its really urgent.
Thanks and hope this helps,
