Hello,
Mostly ovarian
cysts are symptomless But
Ovarian cysts can, however, cause problems if they twist, bleed, or
rupture. Since you have a history of PCOS, it is most likely due to PCOS only. It is less likely for a small ovarian cyst to cause pain. It can cause pain if it becomes large, Bleeds, breaks open, interferes with the blood supply to the ovary, is bumped during sexual intercourseor is twisted or causes twisting (torsion) of the Fallopian tube.
