Hi. Some red spots appear on my chest frequently. It's painless, but itches sometimes a little. It goes on its own. But every time it reappears it grows in numbers. It started with 2-3 spots one year ago but now there are many red spots. This condition stays for 2-3 weeks and heals by itself, then reappears in 4-5 months. Can you please help me identify the condition? I want to search for it on the internet before I go to a doctor. I am attaching some pictures of my chest. Thanks.
