Hi, I have had intense vomiting, diarrhea and cramping since about midnight last night. My heart feels as though it s racing, I have been running a fever, have extreme fatigue, dizziness a pounding headache, and muscle weakness. I took 2 Imodium about one hour ago. I m just wondering if this sounds like a common virus, or if I need to be seen. I would like to know if it s ok to to take Advil along with the Imodium. Thank you for your response.
