A follicular cyst on occasion would rupture and cause acute pelvic pain. Because of this rupture, follicular liquid is released into the peritoneum, but symptoms are only transient. Surgical intervention is rarely necessary if symptoms are passing. A common type of functional cyst, called corpus hemorraghicum, may rupture late in its luteal phase. This causes spontaneous hemorrhage. Constant pain in the lower abdomen, fever, and vomiting, fainting spells could be an indication of hemorrhage. Seek a medical professional if these are experienced. But if the acute pain and loss of blood is self-limited, patients would be reassured that the cysts would dissolve by itself and be recommended mild analgesics to manage the pain. But if it does not, it may be necessary to have it removed surgically.
