My husband was diagnosed with diabetes, insuline dependant, & Hep. C but has not been to Gastrointerologest, yet.The endocrinologist has warned us to watch for infections, bleeding of esophogus or abdomen, dark stools & vomiting. Our primary care Dr. is not available this week to see. He started the nose bleeds about 3 days ago & is getting worse. He is some times light headed & dizzy. Should I take him to the ER?
