Am ovarian cyst on the left side sometimes causes sharp or dull pain on the same side of the lower abdomen, according to Womenshealth.gov. The pain is continual or intermittent. Certain women also experience abdominal pressure, bloating or swelling on the left side.
Less commonly, ovarian cysts lead to pelvic pain, pain during sex, or pain throughout a woman's period, states Womenshealth.gov. Other possible symptoms include aching in the back and thighs, difficulty with urination or bowel movements, increased need to urinate, breast tenderness, or unexplained weight gain. Very rarely, the cysts result in vaginal bleeding. Most ovarian cysts produce no symptoms.
