I have sharp pain sometimes in the right side abdomen. after two or three minutes pain stops automatically. what are the possible reasons?

Right sided pain.: It could be many things. It depends, or one, on exactly where the pain is. People consider the "side" many things. It could be kidney stones, something with your spleen, lung problems. So we need the whole picture - change in going to the bathroom-color of urine, trouble breathing and much more. Could be muscle strain or a cracked rib. You get the picture, you should be examined.
