I have red, itchy patches all over my chest?

If you have developed red, itchy patches on your torso, it could be a condition called pityriasis rosea. This condition usually appears as one large patch followed by several smaller ones on the upper body. It resolves on its own over a few weeks, and there is no specific treatment. You can try applying a fragrance-free moisturizer and avoiding scented soaps and hot water in the shower. If the patches increase in size or number, it's advisable to see a doctor for further evaluation.
