Please get it taken care of because it will give you trouble. I am not going into treatment options but please get treatment. Good luck. ...Read more

Have got kidney stone measuring 0.5mm. Is it big size as the pain keeps coming and going on my side. Is the size big to worry of?

Because stone surfaces are composed of crystals with sharp surgaces plus ureters are typcally both very sensitive to irritation & constrict in response to pain, thus visious cycle. Big stones in renal pelvis do not readily enter ureters. Small stones more easily pass into ureters. Always catch stone to identify which of 4 types with goal to help prevent recurrances. ...Read more
