### input:
Hi. I am a 34 year old female, I m 5 5 , 120 lbs., active (especially since I have a 3 year old-haha). I have been having pain intermittently since before I was pregnant with my son, on both sides of my stomach in the kidney area. It is a sharp pain that comes in waves, no blood in urine . I have had a history of UTIs, but haven t had one in maybe two years. I went to a general practice doctor last year about the pain, and she ordered an ultrasound of my right side (I am not sure why she didn t ultrasound both sides), and she said that I had kidney stones , but they were small and they should pass, she didn t request that I follow up with her. I have continued to have pain on both sides, though not as often. I have recently been experiencing a fluttering feeling on the left side of my back, almost like a muscle spasm , but I know it s not a muscle spasm. I am fairly certain it is my left kidney. Why is this happening?

Hi, Welcome to Chat Doctor, After going through your history it is possible you had small stones on right side, now you have some ureteric colic on left side as you suffered kidney stones, if you have tendency to have stone formation. Please check with Pro surgeon and get your Ultra sonography repeated to find if you have it sometimes it is possible clot is there or stricture is there. You should also check Uric acid and calcium level Urine R&M. Please take plenty of water and avoid dairy products for time being till you get result of investigations. Please do not worry if anything is there it can be treated easily. Take Care. Good Luck.
