Pelvic effusion from 4 points to 2 points is serious?

Patient's question:

50 days without menstruation, went to the hospital for an ultrasound. 4.2 centimeters, 2.4 centimeters. Past treatment history and effectiveness: Previously, no changes have been made. What kind of assistance is desired: Wondering what method is best for quick recovery

Doctor's answer:

Confirming the pelvic effusion based on your current condition is likely caused by chronic inflammation. It generally may lead to symptoms such as menstrual disorders and lower back discomfort. With active anti-inflammatory treatment, it can often heal on its own.
Recommended medication: Levofloxacin + Metronidazole.
It is recommended to actively treat symptoms, pay attention to personal hygiene, avoid spicy and irritating foods, and undergo regular gynecological health check-ups.
Maintain good hygiene and change underwear frequently. If symptoms occur, intravenous treatment is often more effective.
