You suspect you may have endometriosis or adenomyosis

Which endometriosis symptoms mean I should go to the ER?

Endometriosis can cause intense pain, but certain symptoms are not something to “wait out.” Go to the ER if you have sudden, severe pelvic or abdominal pain that’s different from your usual pattern (especially if it’s one-sided), pain with fainting, or pain plus fever/chills, repeated vomiting, or a rigid/distended abdomen. Those combinations can signal emergencies like ovarian torsion, a ruptured cyst, appendicitis, infection, or other acute abdominal problems that can look like an endometriosis flare but require urgent evaluation.


Also seek emergency care for heavy bleeding that’s soaking through pads/tampons rapidly, passing large clots with dizziness or weakness, or any concern for pregnancy with pelvic pain or bleeding (including the possibility of ectopic pregnancy). If you develop chest pain, shortness of breath, or coughing up blood—especially if symptoms cycle with your period—treat that as an emergency as well. After the urgent issue is addressed, our team can help you step back and evaluate the bigger picture: why the symptoms are happening, whether endometriosis/adenomyosis or another overlapping condition is driving them, and what a clear plan toward durable relief could look like—reach out when you’re ready.

Don’t wait out severe pain

If your pelvic or abdominal pain is sudden, different than usual, or comes with fainting, fever/chills, vomiting, a rigid belly, or heavy bleeding, get emergency care now. After you’re safe, our endometriosis and adenomyosis specialists can help identify the cause and build a plan to prevent future,
