Hard : Hard to tell without a picture, but it is possibly dermatitis or eczema. Any chance it is a skin allergy? I would recommend you try a gentle hydrating cleanser such as cerave and use a moisturizing cream such as cetaphil or cerave twice daily. If not improved, consider a trip to a dermatologist for evaluation and treatment options. I hope that helps.

Rash: This rash would likely need to be examined and more history obtained to be able to provide you with useful input about the diagnosis or possible treatment.
