Did your GYN see the ovarian cyst
by doing an ultrasound
scan? The hormone tests like LH, FSH, Prolactin
will certainly give a clue why the cyst has appeared there and what to expect next. Hnece it's better to get them done. Once confirmed that the big cyst has occurred due to hormonal
imbalance then only it makes sense to treat yourself with birth control pills to get rid of the symptoms or otherwise surgical removal will be suggested in case the pain is severe. The big cyst should not grow further as there is a chance of making your ovary bulky, heavy and twisted causing another emergency. Get back for any further query.
