I'm sorry to say it can come back at anytime. Thankfully the one you had resolved itself.
I, too, have been folowed since August with bilateral complex cyst with the left contaning a solid mass.. I experienced some ppain and pressure last week that I contributed to a possible UTI(wrong. Both of my cysts ruptured!! I am currently waiting to see waht my gyn/onc wants to do because the pain that led me to the doctor is still going on even with this resolution. I aam scheduled for complete hysterctomy on Jan 13.
Thanks for the responses. I am relieved that the cyst has resolved itself and I guess I will be more responsive to my body and thanks to this site I will know that what I am feeling is really something and not just my imagination.
xrayu2 - I've read what you are going thru and my prayers and wishes are with you for a successful surgery, speedy recovery and no matter what the results much strength. Be strong, be confident and always try to laugh at least 3x a day (morning, noon and night) it's the best medicine for the soul.
Good luck I will be watching for your posts.
