I have some itchy patches on the side of my arms n on the upper part of the chest, I want to know what they are. They aren't noticeable but I feel then. I found a cream at my house called mometasone furoate cream usp, 0.1%. It relived the itching and the bumps in the patches started to disappear. Unfortunately there wasn't more of it. I want to know if there is anything over the counter I can use.
