Hello from 3-4 days I am having weird numbing sensation in random small patches in my arms and legs. It just happens for a few seconds or minutes. I am also having gas and back head pain problem from few months now and have recently discovered that I have kidney stones (size 3.6, 3.8 respectively in each kidney) and an enlarged liver for which I am taking medication. Can someone suggest if the sensations are due to this kidney/liver issue or something else and what should I do?
