Oh boy, do I hear you on the itchy stuff. Hoping for some calming.

Would an oat bath help? You put some oats in a cloth and hang in the bath, letting it dissolve into the water. When cool you soak. It can be soothing.

Plus, the BEST thing I have ever found for skin rashes is a swim in the salt water. Cuts the itching and inflammation and clears everything out. Not sure if this is practical for you, but wanted to let you know.

Ice of curse too.
