Have you tried a new soap or shampoo lately? Also, is there any particular body part that is the most itchy? Itchiness in the groin area is a signal of possible diabetes, as is itchiness of the feet. You mentioned having surgery lately - it's normal for wounds to be itchy as they heal. One of my secrets to alleviating itchy skin is to buy hair conditioner and, when in the shower, apply it all over and then rinse it off. Try to get one that isn't over-scented as it's possible to be allergic to fragrances. Sometimes, it requires a few applications but it generally does the trick and it's quite mild on the skin.
