Many rashes disappear on their own in a few weeks, but a few weeks can seem like an eternity if your rash is itchy or painful. However, there are ways to get immediate relief.
If your rash isn't severe or infected, you probably just need to soothe irritation at the rash site. Calamine lotion is the most common topical treatment for rashes, but you can also apply a hydrocortisone cream or take an antihistamine. Pampering yourself by soaking in an oatmeal bath is a great way to soothe skin and relieve itching, and if your rash is painful, taking ibuprofen or aspirin should ease pain and inflammation.
