I have had diarrhea and vomited about once daily since 12/22 yet it has been somewhat intermittent, not vomited every day. Went to MedPoint and they thought had flu. Prescribed Immodium and a anti nausea medication. Yesterday, stool was better (a little loose but not watery) did not throw up. Today, have not had a bowel movement and just threw up again. The throwing up is however not excessive, it is involuntary and I just feel a watering in my mouth and a little bit comes out. No fever and feel fine. Is this a flu? or possibly ulcer? Do you think an antibiotic would help?
