A functional ovarian cyst is a fluid-filled sac that forms on the ovary. A sac normally forms during ovulation to hold a maturing egg. Usually the sac goes away after the egg is released. But if the egg is not released, or if the sac closes up after the egg is released, the sac can swell up with fluid. This forms a functional cyst.
These ovarian cysts are different than ovarian growths caused by other problems, such as cancer. Most functional ovarian cysts cause no symptoms and go away on their own. Some cause mild pain. Others can cause severe pain when they break or bleed.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and contact your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
How can you care for yourself at home?
Use heat, such as a hot water bottle, a heating pad set on low, or a warm bath, to relax tense muscles and relieve cramping.
Be safe with medicines. Read and follow all instructions on the label.
If you are not taking a prescription pain medicine, ask your doctor if you can take an over-the-counter medicine.
If the doctor gave you a prescription medicine for pain, take it as prescribed.
Store your prescription pain medicines where no one else can get to them. When you are done using them, dispose of them quickly and safely. Your local pharmacy or hospital may have a drop-off site.
