Therefore, strenuous activities, rapid bending, rapid turning, rapid turning in the horizontal position, sudden emptying of the overfilled bladder or active bowel movements such as diarrhea and constipation should be avoided. If sudden onset of paroxysmal lower abdominal vague or severe pain occurs, which gradually worsens, accompanied by nausea and vomiting, you should be alert to the occurrence of ovarian torsion and should seek prompt medical attention.
