If the following symptoms appear suddenly, go to an emergency room or gynecologist immediately. Do not endure it or wait it out with Korean medicine treatment. (1) Sudden, severe pain on one side of the lower abdomen accompanied by nausea, vomiting, and cold sweats - this may be ovarian cyst torsion (twisting), which cuts off the blood supply to the ovary and can cause necrosis, possibly requiring emergency surgery within hours. (2) Sudden abdominal pain together with abdominal bloating, dizziness, or low blood pressure symptoms - cyst rupture with intra-abdominal bleeding is suspected. (3) A sudden feeling of faintness or as if you might collapse while having a cyst also requires caution.
