I Am 25 Years Of Age Male From India, In

I am 25 years of age male from India, In the year 2016, that is exactly in the month of May i had a mild pain in my left abdomen and later in the end of the month, it eventually the pain was increased and on june i consulted my family doctor for the treatment, later after CT scan, there was 5mm Stone in left kidney (oxalate stones) and for 3 months have took the antibiotics and followed the treatment also. Later i could see there was no pain at all in my abdomen.

Then i have transferred to another state of India from my hometown on November 2016, where after that there was a pain in same lower abdomen on left side and continued for a month, so again on december 2016 i had a CT scan, bu the result shows that i don't have an stones at all in my kidney.

But for the past one month i have a pain in my same place and once in a week , there is a digestive problem also . So kindly guide me what i have to do.
