Mild abdominal pain, like pins and needles, after egg retrieval is usually not a problem . However, sudden onset of severe abdominal pain accompanied by panic, dizziness, drop in body temperature, and cold sweat all over the body should lead to immediate hospitalization or prompt contact with the attending physician, which requires vigilance for intra-abdominal hemorrhage. In addition, abdominal pain that occurs suddenly after egg retrieval is mostly associated with ovarian impaction or torsion. It is common in patients with a large number of eggs retrieved and ascites. If abdominal pain occurs only after 3-5 days of egg retrieval, you should be alert to the possibility of intra-abdominal infection.
