Clogged duct vs mastitis ??

The side of my right boob has been soooo sore for the last day. I’m feeling like I’m starting to get kind of sick like chills/aches and feel like I’m burning up, but I don’t have a temp. My husband says he thinks the side of my boob is starting to get red, I personally don’t see it. I don’t feel any lumps but my boob is soooo sore. Does that circled area look red to anyone ? That’s the exact spot where it’s sore 😩
