Has anyone else experienced a very painful ovarian cyst? I woke up yesterday with severe pain in lower right abdomen. Thought I was having a apendex issues so went to ER and had CT.  It showed nothing wrong with my apendex.  Doctor thinks it was an ovarian cyst that burst and that's what the pain was from. Note: nothing showed on CT to prove or deny that it was a cyst. That is just what he thought bc nothing else showed on the CT.
