The short explanation
No, please do not wait. Sudden severe pain on the side of a known ovarian cyst, especially with vomiting, needs urgent medical attention today. Two possibilities doctors worry about are ovarian torsion, where the ovary twists on its blood supply, and a ruptured cyst that may cause bleeding inside the belly. Torsion is an emergency because the ovary can be damaged if its blood supply is cut off for too long, and quick treatment can often save it. A ruptured cyst may settle on its own but sometimes causes significant bleeding. Only an examination and ultrasound can tell these apart.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Larger cysts are more likely to twist. Pain from torsion often comes suddenly, may come and go, and is commonly accompanied by nausea and vomiting.
- At the hospital, doctors will usually do an ultrasound, blood tests and a pregnancy test. Surgery may be needed.
- If you can, have someone go with you, and take your previous scan report.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell what is causing your pain. It needs urgent examination and a scan.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Could this be torsion or a ruptured cyst?
- What does the scan show today?
- Do I need surgery, and will it affect my ovary?
- What should I watch for after going home?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department now if you have sudden severe pelvic pain with vomiting, fainting, fever or a racing heart.
Get help the same day
- Get care the same day, within hours, even if the pain eases, because torsion can come and go.
