Had 3 previous transvaginal ultrasounds (from 2006 to 2021). discovered a complex cyst on left ovary (growing 2.0 to 2.3 cm within time). have extreme dyspareunia since 2006. constant back pain over the years. now sharp pelvic pain, bloating?

Your personal gynecologist has to deal with these important issues unless you're dissatisfied & you feel that you want another gynecologist to take you on as a patient.

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see a doctor, preferably a gynecologist. Wish you good health!
