For A Few Weeks Now, I've Had These Light Red/pink

For a few weeks now, I've had these light red/pink spots on my legs and a few on my arms. Some are quite big spots. I'm using like a ringworm cream, but the spots don't look like ringworm really and their not itchy. My spots/rashes haven't gone away except for two. Some are getting bigger and some are fading. But I don't even know what it is,my it I'd like too. It's starting on my arms even.
