I have irritated skin. What should I do to help alleviate my symptoms?

Irritated skin. There are 5011 causes of irritated skin, and there's no way on earth tell you without first seeing you, and taking history, and laying my eyeballs upon the lesion. See you dermatologist!
Depends. Depends what's the cause. Application of a good moisturizer, like cerave, aveeno, (oatmeal) cetaphil cream, or nivea creme may help. But, talk to a dermatologist, find out the possible cause.
