Talk to Gynecologist on Gynecologist

My wife had a twin pregnancy. The babies were born 4 months ago, but the abdominal pain has still not gone away and there is also swelling in the uterus. We have shown her to a gynecologist 8 times. According to the ultrasound, there is swelling in the uterus. They give her IV drips, but the pain only goes away for 5 or 6 hours and then it comes back even worse. And now my wife can't even sit down. She has also applied hot water compresses on her abdomen and does abdominal massages every other day, but the pain is still not going away. Tell me any medicine or home remedies."
