stool tests are necessary
Thank you for the qquery.
Such symptoms in first row should be considered as a gastrointestinal infection
is quite characteristic for such issue. Usually intestinal infection gets healed by its own. However if symptoms last longer than few days, medical attention is necessary.
Such symptoms can also indicate partial bowels obstruction due to Crohns disease
I suggest you to visit your doctor and have stool test and stool culture test. Antibiotics might be necessary. If no infection will be found, colonoscopy
should be next.
Hope this will help. Feel free to ask further questions.
