There are several types of common skin rashes and their possible causes are various. The red, bumpy appearance of a rash may be local to a certain area of the body, or may be on several areas of the body. A rash may not be caused by infection and may appear as a scaly patch of skin. In other cases, the rash may be caused by a fungal or bacterial infection and also appear as a scaly patch of skin. Red and itchy bumps and patches on the body may also be a common type of rash. Various viruses, parasites, heat and medicines may be the cause of certain rashes as well. Eczema, also known as atopic dermatitis, is a condition that may lead to itchy or inflamed skin. An allergic reaction to certain medications may also be a possible cause of rash.
The most common types of rash may be eczema, poison ivy and heat rash. If you notice a rash, many recommend seeing a doctor even before trying non-prescription treatments, especially if you experience a rash after taking medication, as this may be due to an allergic reaction from medication and may be life threatening. To treat skin rash, your dermatologist or doctor may recommend several treatments. Anti-itch creams, antihistamines and moisturizing lotions are common over-the-counter treatments for rash. If you uses these non-prescription treatments and the rash does not go away or become milder, it is important to see a doctor.
