question: Two days i ago i either had a stomach flu or food poisoning but I threw up all of the morning until 2:00. For the rest of the day I felt horrible. Then this morning I blew my nose and immediately felt an intense pain in my lower abdomen for the first time. The pain has been on and off throughout the day and can be quite extreme. Could these two events be related? Could it be from dehydration? Should I see a doctor?
