Thank you for the query.
Such symptoms can be caused by urinary tract
infections, urinary tract stones, gall stones, diverticulitis
(left abdominal side) and heart attack
as well. It is advisable to have some diagnostics. You should start with abdominal ultrasound, fool blood work with liver and pancreas enzymes, urine analysis and heart ECG. This tests should tell what are you dealing with. If you find this tests negative, colonoscopy
should be performed.
Hope this will help.
