Hello, which medicine has a good effect on pelvic effusion?

Patient's question:

Checked last month, bilateral lower abdominal pain, bloating

Doctor's answer:

Your condition may be chronic pelvic inflammatory disease. When inflammation occurs in the female pelvic reproductive organs and their surrounding connective tissues, as well as the pelvic peritoneum, it is referred to as pelvic inflammatory disease. This includes endometritis, salpingitis and oophoritis, pelvic connective tissue inflammation, and pelvic peritonitis. It can affect one or multiple sites simultaneously, and there is usually fluid accumulation in the Douglas pouch. Microwave treatment can be considered.
