Hello I share your concern Consistent diarrhoea for few days warrants detailed evaluation to find out the causative organism for it This could be due to infection like bacterial viral or protozoa In my opinion you should take an appointment with your doctor for examination, checking for signs of dehydration and stool test for ova, cyst or protozoa You may require a course of antibiotics under supervision of your doctor Meanwhile maintain good hydration Have plenty of fluids including ORS and fruit juices as much tolerated to counter dehydration and electrolyte imbalances You can have lemon water mixed with salt and sugar Hope this helps you wish you good health and speedy recovery.
