A rash  is a noticeable change in the texture or color of your skin. Your skin may become scaly, bumpy, itchy, or otherwise irritated.
Common symptoms of a skin rash include red, bumpy, scaly, or itchy patches of skin, possibly with blisters or welts. This condition may or may not be due to underlying diseases. Examples of non-disease causes  that can trigger skin rash are hot and humid weather. Too much exposure to sunlight and tight or uncomfortable clothing can also cause a skin rash. It is often accompanied by itchiness, but it is best to not scratch for long as it can lead to blisters.
Some persons are easily prone to developing skin rash while others aren’t. If you are easily susceptible to skin rash, it is best to avoid using harsh soaps, body creams, and perfumes containing common allergy triggers.
