question: My husband has been experiencing muscle twitches/spasm in legs and other random muscles. He complains of weakness in legs, has had some cramping in flank areas, and talks about a firing or iritation along the spinal cord. He has had several blood panels done and the only things our MD has pointed out include level of Creatine Kinase around 500 and low magnesium. He had a CT scan they said liver and spleen slightly enlarged and has a trace amount of blood in his urine.
