There are certain things they never tell you about in pregnancy books.
One such thing is how you can be happily sleeping, then woken with a pain or numbness that you just didn't expect.
I was chatting with a friend the other day and she said she had suffered the same thing when she was pregnant and near the end, but I don't recall ever being warned about this!
Most nights I end up turning over at least once an hour because my hips have gone numb, which in turn makes my legs go numb too as I must be cutting the circulation. This has been happening for several weeks now.
Just recently I have a new one - my shoulders go numb which in turn gives me a dead arm!
So roughly every hour I'm woken up with the feeling that the left or right side of my body has gone numb, I then have to either get out of bed or find a way to turn over to the other side while trying not to scream in pain and wake up the other half!
Oh the joys of being pregnant...
