how long does it take a rash to go away
According to kidshealth.org, diaper rash usually goes away within 2 to 3 days with home care. Home treatment is usually all that is needed for most cases of diaper rash. But in some cases, it can last longer. A diaper rash is often caused by a reaction to disposable diapers, diarrhea, urine or soaps.
One of them, histamine, is responsible for the symptoms that appear on your skin. Depending on the type of reaction and its severity, the duration of symptoms can vary from days to weeks. Hives are the red, itchy bumps that show up due to a food or drug allergy. They normally go away after a few days. However, some cases of chronic hives can last for months or years. Until hives go away, you can relieve symptoms using antihistamines. Meanwhile, allergic contact dermatitis is the rash that results from you touching something you're allergic to.
