If referred for pelvic vein embolization, attend your pre-procedure appointment
Bring imaging results and medication list to all appointments
Return to emergency department immediately for
Sudden severe pelvic pain significantly worse than your usual pain
May indicate ovarian torsion, rupture, or other emergency
Fever above 38.5 degrees Celsius with pelvic pain
Suggests infection requiring urgent treatment
One leg becoming significantly swollen, red, or painful
Could indicate a blood clot (deep vein thrombosis)
Vaginal bleeding not expected with menstruation
Especially if also experiencing pain and dizziness
Dizziness, lightheadedness, or fainting with pelvic pain
May suggest internal bleeding requiring emergency evaluation
Inability to urinate or severe pain with urination
