Might have rosacea?

So I'm not entirely sure if I could have rosacea or something similar, since no professional has ever confirmed it. Without a professional, would you be able to tell by yourself? I go bright red at a lot of things like the heat and such and my cheeks are always red. Could it be rosacea? or do some people just have red cheeks since theyve always been like this.
