How do u get rid of a fever blister,its on my lip its the size of a pimple,what will happen if i pop it,i cant

use any creams or medication or anything like that............|||If you can%26#039;t use any meds (and I would use camphor oil actually because it dries it up quickly), then I don%26#039;t know any alternative other than stay away from salty and acidic foods for a day or so. But do not try to break it open. You will only make it worse. Try cold compresses.
