What Is an Armpit Rash?

Rashes may appear anywhere in the body. The area where the rashes occur may have an unusual appearance, and the person may feel uncomfortable for a few hours to a few days. The prime area for rashes to occur is the armpits. Armpit rashes appear red or scaly white, and long-lasting, recurring, or severe rashes might be a sign of any underlying health condition. Armpit rashes do not appear suddenly, and they begin with irritation and itchiness, which are unbearable in some cases.

There are many treatments to address armpit rashes but determining the cause for the rash helps decide the best treatment. Most rashes are treated easily with over-the-counter (OTC) medications or home remedies. However, before starting with the treatment and preventive measures for future rashes, it is important to know what causes the rash. It is said that the rashes that have been developed due to hot weather disappear quickly, but rashes caused by lifestyle changes and certain skin diseases last longer and require specific treatments.
