Calomine lotion works well for itchy skin
I've always had it and I take zyrtec because creams don't work for me. Even though you're pregnant you are allowed to take the normal dose of zyrtec so if creams don't work try that!
My daughter has ezcema and the Neosporin Ezcema cream works wonders :) it's relives itches fast !
I have eczema myself. Before I was pregnant I was told hot showers are bad. Luke warm is better and Vaseline right after. Should pat dry nit completely dry of to keep moisture in. But during my pregnancy I used 100 pure natural African shea butter. It did wonders for me
