My 3 year old has had a cough and cold for about 3 weeks, she can't seem to shake it off. This morning a rash has appeared on her back and shoulders, does anyone have any ideas what this might be? The spots are flat but bright red. Sorry the picture isn't great, it's difficult to get her to keep still! It's very difficult to get a doctor's appointment in my area so I was hoping someone on here might have an answer. Thanks!
