I got them with my third bub and I know how terrible they are. Thankfully mine didn't get too painful, more of a heavy ache type feeling and they have all but gone. In fact they were gone within a few months of birth. I didn't have any problems whatsoever at delivery. I was just told to take it as easy as possible (difficult in your job). I actually think you can get support underwear if need be.

I just wanted to let you know that I had the same experience and it was a good outcome.
