I was diagnosed with Mononucleosis last night at an Emergency Room. My liver enzymes are elevated above 300 and there is so much bilirubin in my urine that is looks brown in color. I have severe abdominal pain, blurred vision and lightheadedness. My body is also almost too weak to stand. My doctor told me to take ibuprofen and ride it out. Is there anything else I should be doing? I feel too sick and weak to not do anything else about my medical diagnosis.
