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.
Skin rashes can have many causes. Each one pertains to a particular condition of the skin or a particular type of disease. It requires the help of a dermatologist to decide what the problem is and what treatment is to be given.
Contact dermatitis is a rash caused by touching something that was previously contaminated or does not suit your body chemistry. Eczema is a skin problem related to people with allergies and asthma. Sebhoric dermatitis deals with flaky skin. If it is on the scalp, it is called dandruff.
Skin rashes are myriad in nature. Each condition is relative to certain problems. Simple problems occur due to allergies to certain foods, detergents, perfumes, plants, etc. Others could be related to diseases like measles, chicken pox, shingles, hand and foot diseases etc. If the problem is considered serious, then you may be advised to have a skin biopsy to rule out diseases like cancer.
