This is a home remedy that really works quick. I just recently got my first lip sore. Its huge and ugly and very very painful. I have been searching up and down for something to just soothe the pain for a little while, I've tried Ice, Heat, Blistex, Neosporin Lip Medication, everything.
After tryin a few things from this site I was lookin through my bathroom and ran across Lanacane.. I thought, "hey why not?" And OMG just dab a little bit on and rub it in and its like and instant pain begone! Please read the directions first tho! DO NOT SWALLOW..
