I am experiencing rash on my wrists/hands. (quality: itchiness, bumpy) . the following also describe me: burning sensation and skin redness or irritation. 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.

Irritant?: It appears that you have an irritant reaction on your hands and wrists. This may be from excessive hand-washing, exposure to irritants (esp chemical solvents), and possible contact allergens as well. Try wearing non-latex gloves to reduce hand-washing and irritant exposure. A few days of topical cortisone may help calm down the irritation. Apply hand lotion often. See derm doc if persistent.
