An itchy rash may be caused by an irritating substance coming into contact with the skin, known as contact dermatitis, explains Mayo Clinic. Soaps, cosmetics, fragrances, jewelry and plants are often causes of contact dermatitis. Seek medical attention if the rash is extremely uncomfortable, painful, severe, widespread or does not improve within a few weeks.
Treatments for rashes due to contact dermatitis include avoiding the irritant and applying topical steroid creams. If the rash is caused by a fungal infection, which is identifiable by its fiery red color and potential to spread to a large area, then the area of the rash should be cleansed and a thin layer of antifungal ointment applied, according to Cleveland Clinic. A zinc oxide barrier cream can be used once the rash clears to prevent it from returning. Rarely, a patient may require surgery to relieve itching, particularly if it is caused by a skin disease.Learn more about Skin Conditions
