Pelvic effusion, but there is still some discomfort in the lower back and hip area. Do you think it's still necessary?

Patient's question:

Last year miscarried and have been like this until this year, severe for the past month, 7.1cm x 2.5cm

Doctor's answer:

Your condition may be chronic pelvic inflammatory disease. When inflammation occurs in the female pelvic reproductive organs and 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 therapy can be considered.
