Just wanted to say never to feel stupid about asking questions - either here, or your MW/OB. That's what they (and us!) are there for.

I know how bad my itch was and I was scratching the skin red raw and would wake up with blood on my clothes. It kept me awake most of the night and doing things that I would normally find relaxing, e.g. bath/shower were equally as bad. It nearly drove me insane.

Let us know how you get on won't you?
