Bumpy rash - 10 month old

Kayleigh

My little one had a bump rash appear on her front and chest on Thursday night and it’s not going away. She’s got no fever and is absolutely fine in herself. You can feel the bumps more than actually see them.

I just wondered if anyone had experienced this before? I’m stressing out and just wondered if I need to take her Drs next week or if it might be viral and go away on its own?

Thanks in advance!
