My fiancé is a 64 yr old man, who a few days began having severe cramping, and stomach spazms and lots of blood in his stool. Took him to the urgent care center, who advised to take him to his gastroenterologist. That was done yesterday, had blood work done, came back with a 17 on his white blood count, going to have a colonosophy. Please advise as to what could be going on..
