Hmmm hehe I actually came here into the health forum to post about this exact same thing...well I think its the same. I have always broken out on my face mildly, not horribly, but bad enough. I use to break out on my chest and back a bit. But now I get these bumps on the back of my neck, back and sometimes my arms....that are never really pimples they just itch then turn scabby...and take forever to go away!!! Its terrible....what are they?? I think its from stress cuz Im really stressed out. I realized that when i was really stressed out a few times I got a horrible red rash on my back and chest. I couldnt stop scratching . Its really embarassing...I dont want to wear a bathing suit....
could be vitamin deficiancies but otherwise theres probably not much u can do, exfoliate or something! usually its in your genes and you cant do much about it unfortunatly
