My skin itches and it's red. what should i do?

Moisturize: This depends of what is the cause of itching. In general, itching is a sign of inflammation. This could be a result of medications, allergic exposure, or infection. Moisturizer and Hydrocortisone creams over-the-counter generally helps relieve some itch. However, if the cause of the problem is still present, you will continue to itch. If your itch persists, you should see a doctor.

Red itchy skin: Those symptoms mean the skin is irritated. Cool compresses can soothe it and reduce the redness. Hydrocortisone and moisturizers can help with the itching.
