Suggest Me Treatment For Tenderness On Right Side Is It Ovary Or Appendix.

AFTER MY PERIOD THIS MONTH I HAVE TENDERNESS ON THE LOWER RIGHT SIDE, WHEN I SIT I FEEL TENDERNESS UNDER THE BELLY, HOWEVER WHEN I AM LAYING DOWN AND SEARCHING FOR WHERE THE PAIN IS TOWARDS THE HIP AREA WHEN I PRESS DOWN IT HURTS BUT ONLY WHEN I PRESS DOWN AND I AM WONDERING IF IT IS THE OVARY SACK OR THE APPENDIX, THIS HAS BEEN FOR FOUR DAYS NOW AND I HAVE NO FEVER OR ANYTHING AND THE PAIN IS VERY LOW
