Hello, I have been feeling very itchy lately in my whole body for the past few weeks. When i itch, it would go all red, and then I would see little raised bumps but not all the time. Then I started reading up, and I tested my skin , then even if i scratch it without it itching it will show a raised white bump where i scratched with redness surrounding it. It only lasts for like a minute then vanishes! I am wondering if there is any advice you could give?
