I am writing this inquiry out of concern as a red rash suddenly appeared on my face a few days ago. At first, only the area around my cheeks turned slightly red, but now it has spread to my forehead and chin, with bumpy blemishes covering a wide area. The sensation of heat intensifies, especially at night, accompanied by itching; even though I try not to touch it, it keeps bothering me and is causing me stress.
I don't think I've changed my cosmetics or eaten anything particularly bad recently, so I'm not sure what the cause is. It doesn't subside easily even when I try soothing packs at home. If I visit a hospital, is it possible to get an accurate diagnosis of the cause and undergo allergy testing?
Please let me know if there is an ointment prescription or soothing treatment program available for immediate application, or what the various problems are.
