Hi thanks for asking question. Here according to history nothing seems much serious. If you have diarrhea and constipation alternately at few days you might have simple functional bowel disease. If You have only complaint of only incomplete defecation without constipation it might be simple stomach upset or short term flu if stool frequency increased Follow below instruction for few days. Take more water and fruit juice. Cooked oatmeal useful in soothing stomach. Garlic , banana , wheat bran , whole grain like food useful. Glutamine tablet also useful. Do regular exercise. Chamomile in tea useful in relieving irritation of stomach. Mostly with these measures you will recover. If still problem do stool examination that might reveal parasite infection for that albendazole taken. If still symptoms increasing then go for USG examination. I hope you will understand my concern.
