Has anyone else had this and have any wisdom to share???? I've not slept for days cos every time I lie down something else itches and the rash is everywhere except my legs. GP has no idea and all they can give me is a menthol moisturiser which works for all of about 10 minutes and antihistamines which don't work at all. I'm only 19 weeks and I can't cope like this for another 21.
