I am experiencing rash (quality: itchiness, red or bluish purple, flaking or scaling, bumpy) . the following also describe me: burning sensation, flaky skin, dry or cracking skin, skin redness or irritation, and painful skin. what should i do?

Many possibilities..: Itchy spots can be from many causes, such as: hives, viral infections, medication causes, hot-tub rashes, heat rashes, reactions to creams or lotions, allergic reactions to some things (including foods), internal medical disorders, etc... That means a rash that persists or is worrisome in appearance should be examined. Hydrocortisone cream is sometimes used for a week, to decrease a rash or itch.
