Taz - let us know how you go at the clinic. I hear you on medical staff though - I remember going to a clinic because AF was two weeks late and he didn't understand a word I was saying either!
But I wanted to say - calmine lotion is what we use in the hospitals for itchiness. Of course, it doesn't always work. When I get a mozzie bite I use vinegar (actualy works!). Cold compresses are the another great natural remedy (so good on you for getting in a cold shower!). Otherwise - have a chat to your pharmacy for a product you can use to help with the itch - topical is usually best. Do let us know what the clinic says though.
