You have got a pulsating cramp in lower right abdomen below bellybutton slightly to the right of it. It happens just after ejaculation and last for about 10 minutes. The pain is fairly severe when it is happening and if you bend forward it gets much worse. And it is slightly alleviated when you stand up straight or bend back slightly. The possible causes are:ProstatitisEpididymitis or obstruction in the pathways of semen. This can be diagnosed by ;Ultrasonography and color Doppler examination of the abdomen and scrotum. Clinical evaluation to see the probable reason and correct surgically. </s>
