I've never heard of round ligament pain during labor, but I just go off of my experiences and those of the people who post. AFAIK
most round ligament pain happens when you move, when you stretch the ligaments fast.
For me... I had terrible round ligament pain last pregnancy, from very early on. It was my first time dealing with it and I thought there was something wrong with me and ran to the doctor. I know better now.
I did a lot of stretching exercises. I have a yoga tape, and I just generally do slow stretches when I'm feeling stiff. I don't know if it helped, but it made me feel like I was doing something.
When you stand up, stand up straight, dont twist. Keeping your body aligned (knees to hips to shoulders) should really cut down on round ligament pain. Turning (like to get out of bed), turn with your whole body, and not with your waist.
As for relieving one, I didn't ever like taking tylenol etc because it seemed to kick in right after the attack was over, and go away before the next one.
: What worked for me really really well was warm wet compresses to the area. (wet seemed to work a hundred times better than dry, but a heating pad is ok if nothing else is available atm) There may be an herbal remedy that you could add to the mix to help soothe, but last pregnancy I hadn't had enough information about herbs to even consider it and havent had too much trouble this time yet. Maybe someone with more herbal experience would be able to help.
