Hi ! You have not mentioned about your dietary habits. The symptoms what you have mentioned could be due to allergy
to some constituents of your food like lactose or gluten
intolerance. You may have to consult a dietician regarding this. Apart from this you may be having some kind of intestinal infection which may cause such symptoms. To exclude this, you have to get your routine stool testing done, and consult your family physician with the report. Wishing you an early recovery.
