I sometimes get a sharp stinging pain on the middle right side of abdomen doesnt last long a few seconds and its not every day and more stinging then painful what could it be?

It is difficult to say what my be causing your discomfort. For how long have you had this experience. What brings on the discomfort. I would ask that you schedule an appointment with a Physician, and express your concerns. Most likely, an examination, with accompanying X-ray/scan will be necessary to help in determining what might bothering you.
