About a year ago I had a kidney stone but after several days of very painful circumstances I passed it and now have had no further problems regarding this issue. However from Thursday night when I got home from my work I had a very slow pain in my left side. It started from my back and has now moved to the lower part of the left side. Initially I thought I might have another stone but still not sure. So I want to ask from a specialist, what might be the problem?
