I dont know what causes it but I sympathise. My itchy tingly skin is all over and seems to come and go. I had it first around 10 weeks for a number of weeks with no visable rash but itching, and *****les. Now its back again at 26 weeks. I am guessing its something to do with high estrogen levels or a build up of bile salts.

I mentioned it to my ob last time but he Didnt seem too concerned. Oatmeal cream and warm (not hot) showers help but so far no cure here :-( I hope it goes away soon.
