Hi, for the past two weeks I've been observing a skin rash on my hands. They start like little bumps on skin and they change color to medium to dark brown. They're slightly itchy. I'm concerned because they're spreading slowly. I don't have any other problems like a fever or something. I wondered if it was an allergic reaction to a soap I started using only a few weeks back. I stopped using the product soon after observing the rash. But the problem still persists and its growing. I'm concerned if its a chronic problem. I have attached pictures of my hand. Thanks for helping me out.
