Hi,

I've had the same issues with my legs and boobs. The best thing I can recommend, it has been a life saver for me is:

**Pinetarsol Gel available from your chemist, this is the form that you can put on a loofer in the shower and rub all over.
combined with
**Dermaid cream (Category A so safe in preganancy) which you put on once you get out of the shower. (also available @chemist)

This was the best advice and such a god send, after two days I was so longer waking up with scratches all over my body from where I had gone to town overnight!

Good luck, I know how bad the scratching can be!
