Bacterial vaginosis and pain during sex

BV changes the balance of bacteria in the vagina and often causes thin discharge or a noticeable odour. Irritation may make penetration uncomfortable, yet deeper pelvic pain is not explained by BV alone and deserves a clinical check.

Pain at the vaginal opening may come from irritation, dryness, inflammation, or tightening of the pelvic floor muscles. Pain felt deeper in the pelvis can accompany infections affecting the cervix or upper reproductive tract, endometriosis, an ovarian problem, or another pelvic condition.

Changes in discharge, odour, itching, burning when passing urine, bleeding after sex, fever, or pelvic tenderness help a clinician distinguish BV from conditions that need different testing and treatment.

Pause penetrative sex if it hurts. Avoid vaginal douching and scented washes, which can worsen irritation. Arrange an appointment if this is new, recurring, or associated with unusual discharge; examination and a vaginal sample may be offered.

If BV is diagnosed, take the prescribed medicine exactly as directed and complete the course. Mention any possibility of pregnancy, recent antibiotics, new sexual partner, or concern about a sexually transmitted infection so that testing and medication can be chosen appropriately.

Seek urgent medical care for severe or worsening pelvic pain, fever, faintness, vomiting, heavy bleeding, or pain with possible pregnancy. These features require prompt assessment rather than treatment for BV alone.

Book routine care when pain continues after BV treatment, repeatedly returns with sex, or comes with bleeding after intercourse. A clinician can check for cervical irritation, pelvic infection, skin conditions, dryness, or pelvic floor muscle pain.

Ask whether your symptoms fit BV alone, whether a vaginal or cervical sample is needed, and when sex is likely to be comfortable again. You can also ask what to do if symptoms return and whether your medicines interact with alcohol or other treatments.
