Vaginal bleeding, pelvic pain, swelling, tenderness and a malodorous vaginal discharge are some side effects of pessary rings. The pessary may also fall out during a bowel movement or cause difficulty using the bathroom, according to Bringham and Women's Hospital.
A pessary is a soft device placed inside the vagina to support a woman's pelvic organs and treat urinary incontinence, notes Bringham and Women's Hospital. Pessaries that can be cleaned at home should be removed and washed daily with soap and water and allowed to dry before reinsertion. Other pessaries should be removed and cleaned regularly at a doctor's office, recommends Bringham and Women's Hospital.
