Skin rash is defined as skin that is not normal in appearance and texture. It is characterized by redness, bumps, blotches, cracks, blisters or swelling and may be accompanied by itching and, in severe cases, by fever. A rash may be localized or may spread to the entire body. If medical attention is not given on time, the problem can worsen. Dry skin rashes are the most common rashes among all. If you belong to the category of those having dry skin, then you might have bigger chances of developing skin rashes because being dry, your skin will be easily irritated, especially during the cold, dry months of the year.
