Pain on right side

So I have this sharp pain on my right side like under my ribs. It comes and goes. It has been happening all day on and off. When I take a deep breath. When I walk around. When I bend over. And sometimes when I just am sitting/laying down. I am just wondering if anyone has had this sharp pain? And also should I call the on call nurse to see what to do. I have rested and drank water. Let me know please if you have any information!
