Last night I noticed a reddish/brown mark under one of my nipples, maybe about an inch or less long. As far as I know, it wasn't there yesterday morning. It's still there this morning though. Looks a little like a bruise. I googled (lol) and am anxious about IBC.. Online it says if it doesn't go away get checked but it also says IBC is quick and could change in days, so should I try and get an appointment today? Or should I give it more days and see if it fades?
