Thank you for the query.
Your symptoms are most likely caused by gastrointestinal infection
. It can be due to some foods intake contaminated by bacteria. Due to pathological bacteria presence your intestines get irritated what can cause all mentioned by you symptoms.
That is why, the first thing you should do is to start probiotic
intake. Stool tests should be done and proper antibiotic prescribed.
If no infection will be found, colonoscopy
should be the next step to rule inflammatory bowels diseases out.
Hope this will help.
