Hi there, I've been diagnosed with a 5-6 mm calculus noted in upper pole in left kidney through ultrasound a week back. I get lower back pains and shooting pains on my left stomach area at times. Wanted to check if there's anything serious or would it just pass by or should I be using veltam 0.4 tablets. Or kindly suggest me the best solution pls. Reports final impression says: Non obstructive left renal calculus.
