Hi ! I would suggest you to go for a routine stool test
to exclude ova or cyst
of amoeba, which is a very common infection of the gastro intestinal tract. The kind of symptoms you have comes in amebiasis
, which may not be detected in routine stool test. You may discuss with your family physician if you should go for a course of anti amoebic drug or not.
Another way is to see after which particular food you get such symptoms, so that you can exclude the same by repeated trials. Your gastro intestinal tract may not be tolerant to some unsuspecting food items you eat.
Apart from this, you can try some probiotic
drug and add fresh curd regularly to your meals which will improve your symptoms upto some extent.
Wishing you an early recovery.
