My husband has a hard time sleeping at night, has involuntary flexing of his foot while sleeping, wakes with extreme calf or thigh cramps frequently. Of late, maybe 2 months, his urine has been noticeably orange with a different odor. More recently, 3 weeks, he has been having a lot of diarrhea, and today said his stool was orange. We did not have anything orange in the diet recently. Ideas?
