Hello. I've recently moved to USA for higher studied and I've had on and off diarrhea once a while. However, since the past three days. I've been having continuous watery diarrhea. I've had 5 episodes on the first day, 2 on the 2nd day and another 3 times on the third. What could it be? I have not taken any anti diarrheal medication. I do not have any other symptom expect for abdomen tenderness and more tender towards the lower right side. Thank you
