my left kidney feels like it s fluttering, most of the time. I also am living with MS, secondary progressive. I m 63, 67 inches tall and weigh 145 pounds.. I have had a venplasty to do a CCSVI procedure and now have stents in both my jugular veins, which are occluded {quite plugged up, I take Clopidgrel......I tend to blame everything on the MS label , but this flutter might be kidney stones? I was told many years ago that I was making stones. My Dad made stones.
