Oh darl, just found this thread.
The way they have been treating you is just atrocious!
Sounds like you're losing your plug too, and I had the stingy/burning sensations while in labour with Elise when I was dilating just prior to transition.

Threaten them if you have to to get an internal done to check for dilation, and if you need to demand to go to melbourne or dandenong (a friend of mine worked in dandenong's NICU 2 years ago and said they were really good there).

Looking like you've been sunburnt doesn't sound good either, hope the heart scan can tell you what's wrong so it can be fixed up!

Hope everything settles down for you darl xxxx
