Rash is a condition in which the skin becomes red, sometimes breaks out into patches or covers a large part of the body in a short space of time. Most forms of rash cause itching that is often severe. This condition is caused by many diseases, allergies, and activities. Listed below are most of the causes:
In contact dermatitis
Because of the numerous causes, many different remedies are required. The doctor must first determine the cause in order to select the appropriate remedy. In many cases, the patient is afflicted with another disease that causes the rash and proper treatment of the underlying disease will cause the rash to disappear. This is true of measles, lichen planus, lyme disease and many others.
Side affects from drugs usually cause rash from an allergic reaction to the drug. Because a patient may be taking so many different drugs, it is difficult for a doctor to identify the one causing the allergy. All drugs should be discontinued except those absolutely necessary for the patient's life, then after a day or two start taking the drugs one each day to see which one causes the allergic
reaction. Usually the rash will disappear within a few days after discontinuance of the drug.
There are many rashes caused from food allergies and these are difficult to diagnose. A food allergy specialist should be consulted in this type of case to determine the allergic food. There are many tests to discover the food allergy but discontinuing certain foods is one method that usually works. One food after another can be dropped to see if the allergy disappears
There are other conditions and diseases that may cause rash. A dermatologist should be consulted to get expert advice on the condition.
