The question is, that my grandfather and went to subway , and got seafood, and tuna subs with various veggies. Later in the day and the following two days we got very ill, only, there was no throwing up, no watery stools. Only moderate to strong cramping pian, excess stinky gas, constipation and stinky stools, and mild fever and chills. We assumed that in a while it would pass and go away. While the worst of the infection seems to be over, it seems to occur agian, though much more mildly, every time food is eaten, or at random periods during the day. I Was wondering if an antibiotic would help, or if its anything serious. The symptoms have been persisting for about 14 days so far.
The most common diagnostic symptom of an intestinal infection is frequent watery stools (diarrhea), which is missing in you and your grandfather's case. Abdominal cramps, throwing up and fever may be present but not always. Fever and chills indicate that you might be experiencing some type of infection but lack of diarrhea indicates that the infection is not intestinal. Other symptoms (cramps and constipation) could be due to an infection outside the intestinal tract. Maybe there is no infection at all but you both experienced a non-infective poisoning. You can request standard blood analyses to confirm an infection. Then , a microbiological examination of the stool is used to confirm, deny, or identify possible intestinal infection.
