For months now, I've had this patch of extremely itchy pimples and rash between my breasts(some of them ARE pimples, I 'popped' a couple by itching and got cores). They didn't spread until recently, but nothing(creams, cleansers, etc) helped them stop itching or clear up. In the last month, they've spread to cover my entire chest, upper arms(down to short sleeve length), and upper back pretty solidly.
