My son is on his third kidney stone in 4 months and it kills me to watch him in so much pain. They also identified an enlarged lymph node or nodule unspecified somewhere in his abdomen/groin area I think.. Has anyone experienced the nodule/lymph node issue?<a href="http://www.connections4life.com/blog/2011/10/21/CT-Results-In-Kidney-Stone-3-et-al.aspx">http://www.connections4life.com/blog/2011/10/21/CT-Results-In-Kidney-Stone-3-et-al.aspx</a><br>
