side pain

I am 10 months post op and have been having pain in my left side, i went to my surgeon and he ordered a ct scan. Although I have no stones they did find i may have nephrocalcinosis, which is a build up of calcium in the kidneys, so i am deciding to stop the calcium citrate pills and just do the multivitamins. When i had my stomach scan before the surgery they found that it is oblonged (very long) which was why i never felt full. So even though my stomach is now smaller the shape is still the same and i can still get in a complete meal ie protein a side and some veggies (just smaller quantities). With that being said I don't feel I'm vitamin deficient anyway so taking supplements 3x a day maybe an overload and the reason for the build up in my kidneys. I have informed him of this but just looking to get some feedback from actual patients who may have experienced this
