For about two weeks my girlfriend has been experiencing stabbing pain in her abdomen during orgasm. It's located on the lower left side. She says she's had something like this before but it went away on it's own. The pain is not severe, mostly irritating. And the stronger she comes the worse it gets but it stops a short while after.
She heard that it may be caused by kidney stones and similar urinary tract problems, but she doesn't have any other symptoms.
Any suggestions on what is it?
ETA: Thank you to all who answered. If it is indeed a cyst, is there any way to minimize the pain while we wait for her gyn appointment?
