In my opinion you should undergo a urine complete examination and Urine culture examination to rule out urinary tract infection.
Also you need a ultrasound examination of the whole abdomen and X-Ray(K.U.B) for appropriate diagnosis and management.
To rule out U.T.I
To rule out Urinary Calculus,Sludge formation.
You can try some self care remedies in the meantime like
Maintain a good hydration.
Take OTC Advil.
Also warm compresses with a heating pad on affected site.
Take OTC Emetrol for nausea.
Also try AZO pills.
See a doctor at ER if pain gets worse over the time.
