When cysts do lead to symptoms, these can include menstrual irregularities from a hormonal effect, pelvic or low back pain that can vary from mild, occasional
pain to severe, persistent
pain,
pain during intercourse, a feeling of fullness or heaviness in the low abdomen or pelvis, and if the cyst is large enough, pressure on other organs like the bladder or bowel.
Occasionally, cysts can twist on their stalks or rupture, leading to sudden severe pain that should be evaluated ASAP.
