Burning-Not ligament pain

Lesley
I'm 34 w 5 days pregnant and I've been going to a regular OB and perinatal.  They're taking him at 36 weeks because of previous csection incision concerns. With my last one they said they could see through where my first csection incision was-which I had been complaining about a burning pain where I thought the old incision was. 
Changed doctors for this pregnancy and I've been complaining about the same burning sensation for a while. Both my perinate and ref OB say it's round ligament pain. I call bullshit and have gone to the women's hospital ER with the pain where they said the exact same thing.  It's the same burning when they're cutting into you when your epidural isn't working.  If they're so concerned about uterine rupture that they're taking him 4 weeks early then shouldn't they think more into this or is it in my head? It's real bad when I cough but other than that the burning sensation is there all the time. Does anyone else on here get the same burning on old csection sites?
