Also...to better answer your question....There isn't a specific condition that causes both fibroids and cysts. They both grow when hormones are out of balance. But, the two together are not a symptom of a specific condition. Most women have both fibroids and cysts during their lifetime. Fibroids do not go away. But, most are left and not treated unless they grow very large or cause troublesome symptoms (ie, heavy bleeding, pain).
I am so sorry to hear that you have had so many cysts. It seems like the birth control pills are not working. But, they do take several months before they are working completely for hormone regulation. Has your doctor tried different ones? Do you have PCOS? PCOS or endometriosis are underlying conditions that can result in many cysts. Both fibroids and cysts can grow when hormones are out of balance. I think it is time for you to have some further tests and try different pills at the very least. If your current cyst is over 5cm or complex, then you will need surgery to remove it. Talk to your doctor about this problem and hopefully, he/she will have some options for you. If not, then you may want to get a second opinion to get a fresh perspective on this. I hope you feel better soon!
