Symptoms of OHSS include severe pelvic pain, swelling of the hands or legs, abdominal pain and swelling, shortness of breath, weight gain, low urine output, diarrhea, severe nausea, and vomiting. OHSS can be fatal. Notify your doctor immediately or seek emergency medical attention if you develop any of these symptoms.

• an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives);

• pain, warmth, redness, numbness, or tingling in an arm or leg (which may indicate a blood clot);

• confusion, severe dizziness, or severe headache (which may indicate a blood clot in the head); or

• difficulty breathing.
