ok so a few days ago, i slipped and literally ate cement. like my mouth is what broke my fall. ok well so my lips are busted, top and bottem and i knew i would have a scab because it was bleeding. k SO this scab above my mouth, below my nose is YELLOW. what the eff does that mean? so i did a little research and apparantly scabs that are yellow are formed from dried serum= bacteria infection? i dont even know what that MEANS. its kind of an awful feeling because tomorrow im supposed to par-tay for the new year and i have this HIDEOUS yellow scab. gag me. so does anybody know what a yellow scab means? or even how to get rid of it asap. please any help would be nice. my lips have gone down by a large amount. the only thing that is noticable is this thing above my lip.
