Rashes can be red, itchy, scaly or dry. They can appear as blisters, blotches, bumps or wheals. They can occur in one area of the body or all over. It could be due to contact with allergens or irritants, bacteria, virus, psoriasis, urtricaria, eczema, drug rash, heat rash and a variety of other causes. A rash can come in many forms and depending on the cause may take days or weeks to heal. So it is important to see a dermatologist for proper diagnosis and treatment.
